An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. ([CVE-2019-1125](<https://vulners.com/cve/CVE-2019-1125>) also known as Spectre SWAPGS gadget vulnerability)
A Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with unprivileged local access could use this information to reveal private data through a Spectre-like side channel.
Impact
F5 continues to investigate the impact of the Spectre SWAPGS gadget vulnerability on our products. F5 is focused on providing patched releases as soon as we have fully tested and verified fixes. F5 will update this article with the most current information as soon as it is confirmed.
BIG-IP
First and foremost, there is no exposure on BIG-IP products by way of the data plane. All exposure is limited to the control plane (also known as the management plane).
Furthermore, on the control plane, the vulnerability is exploitable only by four authorized, authenticated account roles: Administrator, Resource Administrator, Manager, and iRules Manager. You must be authorized to access the system in one of these roles to even attempt to exploit the vulnerability.
This vulnerability requires an attacker who can provide and run binary code of their choosing on the BIG-IP platform.
These conditions severely restrict the exposure risk of BIG-IP products.
For single-tenancy products, such as a standalone BIG-IP appliance, the risk is limited to a local, authorized user using this vulnerability to read information from memory that they would not normally be able to access, exceeding their privileges. Effectively, the risk in a single-tenancy situation is that a user may be able to access kernel-space memory, instead of being limited to their own user-space.
For multi-tenancy environments, such as cloud, VE, and Virtual Clustered Multiprocessing (vCMP), the same local risk applies as with single-tenancy environments - local kernel memory access. Additionally, the risk of attacks across guests exists, or attacks against the hypervisor/host. In cloud and VE environments, preventing these new attacks falls on the hypervisor/host platform, outside the scope of F5's ability to support or patch. Please contact your cloud provider or hypervisor vendor to ensure that their platforms or products are protected against this Spectre vulnerability.
For vCMP environments, F5 believes that while the Spectre SWAPGS gadget vulnerability does offer a theoretical possibility of guest-to-guest or guest-to-host attacks, these would be very difficult to successfully conduct in the BIG-IP environment.
F5 is working with our hardware component vendors to determine the scope of this vulnerability across our various generations of hardware platforms. All of the information we currently have from our vendors is represented in this Security Advisory.
We are also testing the fixes produced by the Linux community. We are conducting an extensive test campaign to characterize the impact of the fixes on system performance and stability to ensure, as best we can, a good experience for our customers. We do not want to rush the process and release fixes without a full understanding of any potential issues. Given the limited exposure, as detailed above, the complexity of the fixes, and the potential issues that we and others have seen, we believe a detailed approach is warranted and that rushing a fix could result in an impact to system stability or unacceptable performance costs. We will update this article with details of our fixes as they become available.
To determine if this vulnerability affects a platform and the processor type each platform uses, refer to the following table.
**Note**: In the following table, only one entry is shown for platform models that may have several variants. For example, BIG-IP 11000, BIG-IP 11050, BIG-IP 11050F, and BIG-IP 11050N are all vulnerable and included in the table as "BIG-IP 110x0". Some platforms may have multiple vendor processors, such as the iSeries platforms, which have one or more Intel core processors and may have a vulnerable ARM processor in one or more subsystems. F5 does not believe that ARM processors in these subsystems are accessible to attackers, unless some other code-execution vulnerability is present, but the information is being provided out of an abundance of caution.

{"nessus": [{"lastseen": "2023-05-18T15:05:30", "description": "An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125also known as Spectre SWAPGS gadget vulnerability)\n\nA Spectre gadget was found in the Linux kernel's implementation of system interrupts. An attacker with unprivilegedlocal access could use this information to reveal private data through a Spectre-like side channel.\n\nImpact\n\nF5 continues to investigate the impact of the Spectre SWAPGS gadget vulnerability on our products. F5 is focused onproviding patched releases as soon as we have fully tested and verified fixes. F5 will update this article with the most current information as soon as it is confirmed.\n\nBIG-IP\n\nFirst and foremost, there is no exposure on BIG-IP products by way ofthe data plane. All exposure is limited to the control plane (also known as the management plane).\n\nFurthermore, on the control plane, the vulnerability is exploitable only by four authorized, authenticated account roles: Administrator, Resource Administrator, Manager, and iRules Manager. You must be authorized to access the system in one of these roles to even attempt to exploit the vulnerability.\n\nThis vulnerability requires an attacker who can provideand runbinary code of their choosing on the BIG-IP platform.\n\nThese conditions severely restrict the exposure risk of BIG-IP products.\n\nFor single-tenancy products, such as astandalone BIG-IP appliance, the risk is limited to a local, authorized user using this vulnerability to read information from memory that they would not normally be able to access, exceeding their privileges. Effectively, the risk in a single-tenancy situation is that a user may be able to access kernel-space memory, instead of being limited to their own user-space.\n\nFor multi-tenancy environments, such as cloud, VE, and Virtual Clustered Multiprocessing (vCMP), the same local risk applies as with single-tenancy environments local kernel memory access. Additionally, the risk of attacks across guests exists, or attacks against the hypervisor/host. In cloud and VE environments, preventing these new attacks falls on the hypervisor/host platform, outside the scope of F5's ability to support or patch. Please contact your cloud provider or hypervisor vendor to ensure that their platforms or products are protected against this Spectre vulnerability.\n\nFor vCMP environments, F5 believes that while the Spectre SWAPGS gadget vulnerability does offer a theoretical possibility of guest-to-guest or guest-to-host attacks, these would be very difficult to successfully conduct in the BIG-IP environment.\n\nF5 is working with our hardware component vendors to determine the scope of this vulnerability across our various generations of hardware platforms. All of the information we currently have from our vendors is represented in this Security Advisory.\n\nWe are also testing the fixes produced by the Linux community. We are conducting anextensive test campaign to characterize the impact of the fixes on system performance and stabilityto ensure, as best we can, a good experience for our customers. We do not want to rush the process and release fixes without a full understanding of any potential issues. Given the limited exposure, as detailed above, the complexity of the fixes, and the potential issues that we and others have seen, we believe a detailed approach is warranted and that rushing a fix could result in an impact to system stability or unacceptable performance costs. We will update this article with details of our fixes as they become available.\n\nTo determine if this vulnerability affects aplatform and the processor type each platform uses, refer to the following table.\n\nNote : In the following table, only one entry is shown for platform models that may have several variants. For example, BIG-IP 11000, BIG-IP 11050, BIG-IP 11050F, and BIG-IP 11050N are all vulnerable and included in the table as 'BIG-IP 110x0'. Some platforms may have multiple vendor processors, such as the iSeries platforms, which have one or more Intel core processors and may have a vulnerable ARM processor in one or more subsystems. F5 does not believe that ARM processors in these subsystems are accessible to attackers, unless some other code-execution vulnerability is present, but the information is being provided out of an abundance of caution.\n\nModel Processor type Vulnerable to CVE-2019-1125Spectre SWAPGS gadget vulnerability VIPRION B21x0 Intel Y VIPRION B2250 Intel Y VIPRION B4100 AMD Y VIPRION B4200 AMD Y VIPRION B43x0 Intel Y VIPRION B44x0 Intel Y BIG-IP 800 Intel Y BIG-IP 1600 Intel Y BIG-IP 3600 Intel Y BIG-IP 3900 Intel Y BIG-IP2xx0 Intel Y BIG-IP4xx0 Intel Y BIG-IP5xx0 Intel Y BIG-IP7xx0 Intel Y BIG-IP10xx0 Intel Y BIG-IP12xx0 Intel Y BIG-IPi2x00 Intel, ARM Y BIG-IPi4x00 Intel, ARM Y BIG-IPi5x00 Intel, ARM Y BIG-IPi7x00 Intel, ARM Y BIG-IPi10x00 Intel, ARM Y BIG-IP6400 AMD Y BIG-IP6900 AMD Y BIG-IP89x0 AMD Y BIG-IP110x0 AMD Y\n\nNote : Platform models that have reached End of Technical Support (EoTS) will not be evaluated.

This CVE ID is unique\nfrom CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125also known as Spectre\nSWAPGS gadget vulnerability)\n\nA Spectre gadget was found in the Linux kernel's implementation of\nsystem interrupts. An attacker with unprivilegedlocal access could use\nthis information to reveal private data through a Spectre-like side\nchannel.\n\nImpact\n\nF5 continues to investigate the impact of the Spectre SWAPGS gadget\nvulnerability on our products. F5 is focused onproviding patched\nreleases as soon as we have fully tested and verified fixes. F5 will\nupdate this article with the most current information as soon as it is\nconfirmed.\n\nBIG-IP\n\nFirst and foremost, there is no exposure on BIG-IP products by way\nofthe data plane. All exposure is limited to the control plane (also\nknown as the management plane).\n\nFurthermore, on the control plane, the vulnerability is exploitable\nonly by four authorized, authenticated account roles: Administrator,\nResource Administrator, Manager, and iRules Manager. You must be\nauthorized to access the system in one of these roles to even attempt\nto exploit the vulnerability.\n\nThis vulnerability requires an attacker who can provideand runbinary\ncode of their choosing on the BIG-IP platform.\n\nThese conditions severely restrict the exposure risk of BIG-IP\nproducts.\n\nFor single-tenancy products, such as astandalone BIG-IP appliance, the\nrisk is limited to a local, authorized user using this vulnerability\nto read information from memory that they would not normally be able\nto access, exceeding their privileges. Effectively, the risk in a\nsingle-tenancy situation is that a user may be able to access\nkernel-space memory, instead of being limited to their own user-space.\n\nFor multi-tenancy environments, such as cloud, VE, and Virtual\nClustered Multiprocessing (vCMP), the same local risk applies as with\nsingle-tenancy environments local kernel memory access. Additionally,\nthe risk of attacks across guests exists, or attacks against the\nhypervisor/host. In cloud and VE environments, preventing these new\nattacks falls on the hypervisor/host platform, outside the scope of\nF5's ability to support or patch. Please contact your cloud provider\nor hypervisor vendor to ensure that their platforms or products are\nprotected against this Spectre vulnerability.\n\nFor vCMP environments, F5 believes that while the Spectre SWAPGS\ngadget vulnerability does offer a theoretical possibility of\nguest-to-guest or guest-to-host attacks, these would be very difficult\nto successfully conduct in the BIG-IP environment.\n\nF5 is working with our hardware component vendors to determine the\nscope of this vulnerability across our various generations of hardware\nplatforms. All of the information we currently have from our vendors\nis represented in this Security Advisory.\n\nWe are also testing the fixes produced by the Linux community. We are\nconducting anextensive test campaign to characterize the impact of the\nfixes on system performance and stabilityto ensure, as best we can, a\ngood experience for our customers. We do not want to rush the process\nand release fixes without a full understanding of any potential\nissues. Given the limited exposure, as detailed above, the complexity\nof the fixes, and the potential issues that we and others have seen,\nwe believe a detailed approach is warranted and that rushing a fix\ncould result in an impact to system stability or unacceptable\nperformance costs. We will update this article with details of our\nfixes as they become available.\n\nTo determine if this vulnerability affects aplatform and the processor\ntype each platform uses, refer to the following table.\n\nNote : In the following table, only one entry is shown for platform\nmodels that may have several variants. For example, BIG-IP 11000,\nBIG-IP 11050, BIG-IP 11050F, and BIG-IP 11050N are all vulnerable and\nincluded in the table as 'BIG-IP 110x0'. Some platforms may have\nmultiple vendor processors, such as the iSeries platforms, which have\none or more Intel core processors and may have a vulnerable ARM\nprocessor in one or more subsystems. F5 does not believe that ARM\nprocessors in these subsystems are accessible to attackers, unless\nsome other code-execution vulnerability is present, but the\ninformation is being provided out of an abundance of caution.\n\nModel Processor type Vulnerable to CVE-2019-1125Spectre SWAPGS gadget\nvulnerability VIPRION B21x0 Intel Y VIPRION B2250 Intel Y VIPRION\nB4100 AMD Y VIPRION B4200 AMD Y VIPRION B43x0 Intel Y VIPRION B44x0\nIntel Y BIG-IP 800 Intel Y BIG-IP 1600 Intel Y BIG-IP 3600 Intel Y\nBIG-IP 3900 Intel Y BIG-IP2xx0 Intel Y BIG-IP4xx0 Intel Y BIG-IP5xx0\nIntel Y BIG-IP7xx0 Intel Y BIG-IP10xx0 Intel Y BIG-IP12xx0 Intel Y\nBIG-IPi2x00 Intel, ARM Y BIG-IPi4x00 Intel, ARM Y BIG-IPi5x00 Intel,\nARM Y BIG-IPi7x00 Intel, ARM Y BIG-IPi10x00 Intel, ARM Y BIG-IP6400\nAMD Y BIG-IP6900 AMD Y BIG-IP89x0 AMD Y BIG-IP110x0 AMD Y\n\nNote : Platform models that have reached End of Technical Support\n(EoTS) will not be evaluated.

F5 is focused onproviding patched releases as soon as we have fully tested and verified fixes. F5 will update this article with the most current information as soon as it is confirmed.\n\nBIG-IP\n\nFirst and foremost, there is no exposure on BIG-IP products by way ofthe data plane. All exposure is limited to the control plane (also known as the management plane).\n\nFurthermore, on the control plane, the vulnerability is exploitable only by four authorized, authenticated account roles: Administrator, Resource Administrator, Manager, and iRules Manager. You must be authorized to access the system in one of these roles to even attempt to exploit the vulnerability.\n\nThis vulnerability requires an attacker who can provideand runbinary code of their choosing on the BIG-IP platform.\n\nThese conditions severely restrict the exposure risk of BIG-IP products.\n\nFor single-tenancy products, such as astandalone BIG-IP appliance, the risk is limited to a local, authorized user using this vulnerability to read information from memory that they would not normally be able to access, exceeding their privileges. Effectively, the risk in a single-tenancy situation is that a user may be able to access kernel-space memory, instead of being limited to their own user-space.\n\nFor multi-tenancy environments, such as cloud, VE, and Virtual Clustered Multiprocessing (vCMP), the same local risk applies as with single-tenancy environments local kernel memory access. Additionally, the risk of attacks across guests exists, or attacks against the hypervisor/host. In cloud and VE environments, preventing these new attacks falls on the hypervisor/host platform, outside the scope of F5's ability to support or patch. Please contact your cloud provider or hypervisor vendor to ensure their platforms or products are protected against Spectre-NG.\n\nFor vCMP environments, F5 believes that while the Spectre-NG Variant 1.1 attackdoes offer a theoretical possibility of guest-to-guest or guest-to-host attacks, these would be very difficult to successfully conduct in the BIG-IP environment.\n\nF5 is working with our hardware component vendors to determine the scope of this vulnerability across our various generations of hardware platforms. All of the information we currently have from our vendors is represented in this Security Advisory. We are working to obtain the remaining information from our vendors and will update the security advisory as we receive new information regarding our hardware platforms.\n\nWe are also testing the fixes produced by the Linux community. We are conducting anextensive test campaign to characterize the impact of the fixes on system performance and stabilityto ensure, as best we can, a good experience for our customers. We do not want to rush the process and release fixes without a full understanding of any potential issues. Given the limited exposure, as detailed above, the complexity of the fixes, and the potential issues that we and others have seen, we believe a detailed approach is warranted and that rushing a fix could result in an impact to system stability or unacceptable performance costs. We will update this article with details of our fixes as they become available.\n\nTo determine if this vulnerability affects aplatform and the processor type each platform uses, refer to the following table.\n\nNote : In the following table, only one entry is shown for platform models that may have several variants.

Some platforms may have multiple vendor processors, such as the iSeries platforms, which have one or more Intel core processors and may have a vulnerable ARM processor in one or more subsystems. F5 does not believe that ARM processors in these subsystems are accessible to attackers, unless some other code-execution vulnerability is present, but the information is being provided out of an abundance of caution.\n\nModel Processor type Vulnerable to CVE-2018-3693 Spectre-NG Variant 1.1 VIPRION B21x0 Intel Y VIPRION B2250 Intel Y VIPRION B4100 AMD Y VIPRION B4200 AMD Y VIPRION B43x0 Intel Y VIPRION B44x0 Intel Y BIG-IP 800 Intel Y** BIG-IP 1600 Intel Y** BIG-IP 3600 Intel Y** BIG-IP 3900 Intel Y** BIG-IP2xx0 Intel Y BIG-IP4xx0 Intel Y BIG-IP5xx0 Intel Y BIG-IP7xx0 Intel Y BIG-IP10xx0 Intel Y BIG-IP12xx0 Intel Y BIG-IPi2x00 Intel, ARM Y BIG-IPi4x00 Intel, ARM Y BIG-IPi5x00 Intel, ARM Y BIG-IPi7x00 Intel, ARM Y BIG-IPi10x00 Intel, ARM Y BIG-IP6400 AMD Y BIG-IP6900 AMD Y BIG-IP89x0 AMD Y BIG-IP110x0 AMD Y\n\n**Intel and AMD have not responded to requests for information relating to the specific processors used in these platforms.\nTherefore, based on their public statements and in the interests of security, F5 will proceed as if these platforms are vulnerable.\n\nNote : Platform models that have reached End of Technical Support (EoTS) will not be evaluated.

For example, BIG-IP 11000,\nBIG-IP 11050, BIG-IP 11050F, and BIG-IP 11050N are all vulnerable and\nincluded in the table as 'BIG-IP 110x0'. Some platforms may have\nmultiple vendor processors, such as the iSeries platforms, which have\none or more Intel core processors and may have a vulnerable ARM\nprocessor in one or more subsystems. F5 does not believe that ARM\nprocessors in these subsystems are accessible to attackers, unless\nsome other code-execution vulnerability is present, but the\ninformation is being provided out of an abundance of caution.\n\nModel Processor type Vulnerable to CVE-2018-3693 Spectre-NG Variant\n1.1 VIPRION B21x0 Intel Y VIPRION B2250 Intel Y VIPRION B4100 AMD Y\nVIPRION B4200 AMD Y VIPRION B43x0 Intel Y VIPRION B44x0 Intel Y BIG-IP\n800 Intel Y** BIG-IP 1600 Intel Y** BIG-IP 3600 Intel Y** BIG-IP 3900\nIntel Y** BIG-IP2xx0 Intel Y BIG-IP4xx0 Intel Y BIG-IP5xx0 Intel Y\nBIG-IP7xx0 Intel Y BIG-IP10xx0 Intel Y BIG-IP12xx0 Intel Y BIG-IPi2x00\nIntel, ARM Y BIG-IPi4x00 Intel, ARM Y BIG-IPi5x00 Intel, ARM Y\nBIG-IPi7x00 Intel, ARM Y BIG-IPi10x00 Intel, ARM Y BIG-IP6400 AMD Y\nBIG-IP6900 AMD Y BIG-IP89x0 AMD Y BIG-IP110x0 AMD Y\n\n**Intel and AMD have not responded to requests for information\nrelating to the specific processors used in these platforms.\nTherefore, based on their public statements and in the interests of\nsecurity, F5 will proceed as if these platforms are vulnerable.\n\nNote : Platform models that have reached End of Technical Support\n(EoTS) will not be evaluated. For more information, refer toK4309: F5\nplatform lifecycle support policy.\n\nBIG-IQ and Enterprise Manager\n\nSystems with microprocessors that use speculative execution and\nindirect branch prediction may allow unauthorized disclosure of\ninformation to an attacker with local user access by way ofa\nside-channel analysis.\n\nTo determine if this vulnerability affects each platform and the\nprocessor type each platform uses, refer to the following table.\n\nModel Processor type Vulnerable to CVE-2018-3693 Spectre-NG Variant\n1.1 BIG-IQ 7000 Intel Y Enterprise Manager 4000 Intel Y**\n\n**Intel hasnot responded to requests for information relating to the\nspecific processors used in these platforms.

(CVE-2019-11833)\n\n - ** DISPUTED ** An issue was discovered in ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: This has been disputed as not an issue.\n (CVE-2019-12378)\n\n - ** DISPUTED ** An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL. (CVE-2019-12381)\n\n - A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost. (CVE-2018-16871)\n\n - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)\n\n - In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel through 5.2.1, a malicious USB device can send an HID report that triggers an out-of-bounds write during generation of debugging messages. (CVE-2019-13631)\n\n - ** DISPUTED ** An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL pointer dereference. (CVE-2019-12382)\n\n - In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker).

(CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable. (CVE-2017-17805)\n\n - The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.) Limited remote exploitation may be possible, as demonstrated by latency differences in accessing public files from an Apache HTTP Server.\n (CVE-2019-5489)\n\n - An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11.\n It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. (CVE-2018-17972)\n\n - Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff.\n (CVE-2019-11477)\n\n - A double-free can happen in idr_remove_all() in lib/idr.c in the Linux kernel 2.6 branch.

(CVE-2017-17805)\n\n - The mincore() implementation in mm/mincore.c in the\n Linux kernel through 4.19.13 allowed local attackers to\n observe page cache access patterns of other processes on\n the same system, potentially allowing sniffing of secret\n information. (Fixing this affects the output of the\n fincore program.) Limited remote exploitation may be\n possible, as demonstrated by latency differences in\n accessing public files from an Apache HTTP Server.\n (CVE-2019-5489)\n\n - An issue was discovered in the proc_pid_stack function\n in fs/proc/base.c in the Linux kernel through 4.18.11.\n It does not ensure that only root may inspect the kernel\n stack of an arbitrary task, allowing a local attacker to\n exploit racy stack unwinding and leak kernel task stack\n contents. (CVE-2018-17972)\n\n - Jonathan Looney discovered that the\n TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an\n integer overflow in the Linux kernel when handling TCP\n Selective Acknowledgments (SACKs). A remote attacker\n could use this to cause a denial of service. This has\n been fixed in stable kernel releases 4.4.182, 4.9.182,\n 4.14.127, 4.19.52, 5.1.11, and is fixed in commit\n 3b4929f65b0d8249f19a50245cd88ed1a2f78cff.\n (CVE-2019-11477)\n\n - A double-free can happen in idr_remove_all() in\n lib/idr.c in the Linux kernel 2.6 branch. An\n unprivileged local attacker can use this flaw for a\n privilege escalation or for a system crash and a denial\n of service (DoS). (CVE-2019-3896)\n\n - An information disclosure vulnerability exists when\n certain central processing units (CPU) speculatively\n access memory, aka 'Windows Kernel Information\n Disclosure Vulnerability'. This CVE ID is unique from\n CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)\n\n - Jonathan Looney discovered that the TCP retransmission\n queue implementation in tcp_fragment in the Linux kernel\n could be fragmented when handling certain TCP Selective\n Acknowledgment (SACK) sequences. A remote attacker could\n use this to cause a denial of service. This has been\n fixed in stable kernel releases 4.4.182, 4.9.182,\n 4.14.127, 4.19.52, 5.1.11, and is fixed in commit\n f070ef2ac66716357066b683fb0baf55f8191a2e.\n (CVE-2019-11478)\n\n - Jonathan Looney discovered that the Linux kernel default\n MSS is hard-coded to 48 bytes. This allows a remote peer\n to fragment TCP resend queues significantly more than if\n a larger MSS were enforced. A remote attacker could use\n this to cause a denial of service. This has been fixed\n in stable kernel releases 4.4.182, 4.9.182, 4.14.127,\n 4.19.52, 5.1.11, and is fixed in commits\n 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and\n 5f3e2bf008c2221478101ee72f5cb4654b9fc363.\n (CVE-2019-11479)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"http://security.gd-linux.com/notice/NS-SA-2019-0177\");\n script_set_attribute(attribute:\"solution\", value:\n\"Upgrade the vulnerable CGSL kernel packages.

has kernel packages installed that are affected by multiple vulnerabilities:\n\n - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable. (CVE-2017-17805)\n\n - Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. (CVE-2018-12207)\n\n - An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11.\n It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents. (CVE-2018-17972)\n\n - In sk_clone_lock of sock.c, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions:\n Android kernel.

(CVE-2019-11135)\n\n - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)\n\n - An issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.\n (CVE-2019-11810)\n\n - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system. (CVE-2019-14821)\n\n - An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. (CVE-2019-3900)\n\n - The mincore() implementation in mm/mincore.c in the Linux kernel through 4.19.13 allowed local attackers to observe page cache access patterns of other processes on the same system, potentially allowing sniffing of secret information. (Fixing this affects the output of the fincore program.)

etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :\n\n - A new software page cache side channel attack scenario was discovered in operating systems that implement the very common 'page cache' caching mechanism. A malicious user/process could use 'in memory' page-cache knowledge to infer access timings to shared memory and gain knowledge which can be used to reduce effectiveness of cryptographic strength by monitoring algorithmic behavior, infer access patterns of memory to determine code paths taken, and exfiltrate data to a blinded attacker through page-granularity access times as a side-channel.\n\n - The Salsa20 encryption algorithm in the Linux kernel, before 4.14.8, does not correctly handle zero-length inputs. This allows a local attacker the ability to use the AF_ALG-based skcipher interface to cause a denial of service (uninitialized-memory free and kernel crash) or have an unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 are vulnerable.\n\n - An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel. An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace.

A malicious\n user/process could use 'in memory' page-cache knowledge\n to infer access timings to shared memory and gain\n knowledge which can be used to reduce effectiveness of\n cryptographic strength by monitoring algorithmic\n behavior, infer access patterns of memory to determine\n code paths taken, and exfiltrate data to a blinded\n attacker through page-granularity access times as a\n side-channel.\n\n - The Salsa20 encryption algorithm in the Linux kernel,\n before 4.14.8, does not correctly handle zero-length\n inputs. This allows a local attacker the ability to use\n the AF_ALG-based skcipher interface to cause a denial\n of service (uninitialized-memory free and kernel crash)\n or have an unspecified other impact by executing a\n crafted sequence of system calls that use the\n blkcipher_walk API. Both the generic implementation\n (crypto/salsa20_generic.c) and x86 implementation\n (arch/x86/crypto/salsa20_glue.c) of Salsa20 are\n vulnerable.\n\n - An issue was discovered in the proc_pid_stack function\n in fs/proc/base.c in the Linux kernel. An attacker with\n a local account can trick the stack unwinder code to\n leak stack contents to userspace.

The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks.\n\n - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions past bounds check. The flaw relies on the presence of a precisely-defined instruction sequence in the privileged code and the fact that memory writes occur to an address which depends on the untrusted value. Such writes cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to influence speculative execution and/or read privileged memory by conducting targeted cache side-channel attacks.\n\n - A flaw named SegmentSmack was found in the way the Linux kernel handled specially crafted TCP packets. A remote attacker could use this flaw to trigger time and calculation expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() functions by sending specially modified packets within ongoing TCP sessions which could lead to a CPU saturation and hence a denial of service on the system.
