Astra Linux – Vulnerability in Linux, Linux 5.10

There is a use-after-free in the Linux kernel’s tcnewtfilter module, which could allow a local attacker to gain privilege escalation. This vulnerability requires unprivileged user namespaces for exploitation. We recommend upgrading to a version after commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b...

Astra Linux – Vulnerability in xorg-server

A out-of-bounds write flaw was discovered in the X.Org X server and Xwayland within DRIGetBuffers/DRIGetBuffersWithFormat. A client that requests multiple DRI2BufferBackLeft attachments and one DRI2BufferFrontLeft can trigger a out-of-bounds heap write. This vulnerability could be exploited to...

Astra Linux – Vulnerability in Linux, Linux 5.10

The vmwgfx driver contains a local privilege escalation vulnerability that allows unprivileged users to gain access to files opened by other processes on the system through a dangling ‘file’ pointer...

Astra Linux – Vulnerability in Intel Microcode

Unauthorized error injection in IntelR SGX or IntelR TDX for certain IntelR XeonR processors may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10

An integer coercion error was detected in the openvswitch kernel module. When there are a sufficient number of actions, while copying and reserving memory for a new action of a new flow, the reservesfasize function does not return -EMSGSIZE as expected. This could potentially lead to an...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

A use-after-free vulnerability exists in the netfilter component of the Linux kernel’s nftables module, which can be exploited to achieve local privilege escalation. The nftverdictinit function allows positive values to be used as drop errors within the hook verdict. As a result, the nfhookslow...

Astra Linux – Vulnerability in Linux, Linux 5.10

The file net/netfilter/nfdupnetdev.c in the Linux kernel versions 5.4 through 5.6.10 allows local users to gain privileges due to a heap-out-of-bounds write. This issue is related to the nftablesoffload mechanism...

Astra Linux – Vulnerability in Systemd

It was discovered that a Systemd service that uses the DynamicUser property can obtain new privileges by executing SUID binaries. This allows the service to create binaries belonging to the transient group, with the setgid bit set. A local attacker could exploit this flaw to access resources that...

Astra Linux – Vulnerability in Linux, Linux 5.10

A heap buffer overflow flaw was discovered in the IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with normal user privileges to overwrite kernel heap objects and may lead to a local privilege escalation attack...

Astra Linux – Vulnerability in Linux

A use-after-free occurred in the function hcisockboundioctl of the Linux kernel’s HCI subsystem. This issue arises when the user calls ioct HCIUNBLOCKADDR, or when the call to hciunregisterdev triggers a race condition, along with the calls hcisockblacklistadd, hcisockblacklistdel, hcigetconninfo...

Astra Linux – Vulnerability in Jetty9

In Eclipse Jetty versions 1.0 through 9.4.32.v20200930, 10.0.0alpha1 through 10.0.0.beta2, and 11.0.0alpha1 through 11.0.0.beta2O, on Unix-like systems, the system’s temporary directory is shared among all users on that system. A collocated user can observe the process of creating a temporary...

Astra Linux – Vulnerability in Intel Microcode

The sequence of processor instructions may lead to unexpected behavior on some Intel processors. This could potentially allow an authenticated user to enable privilege escalation, information disclosure, or denial of service through local access...

Astra Linux – Vulnerability in PackageKit

PackageKit is a D-Bus abstraction layer that allows users to manage packages in a secure manner using an API that works across different distros and architectures. PackageKit, from version 1.0.2 to 1.3.4, is vulnerable to a time-of-check time-of-use TOCTOU race condition involving transaction...

Astra Linux – Vulnerability in Linux, Linux 5.10

In various setup methods of the USB gadget subsystem, there is a possibility of unauthorized writing due to an incorrect flag check. This could lead to a local escalation of privileges without the need for additional execution privileges. User interaction is not required for exploitation. Product...

Astra Linux – Vulnerability in Cpio

In all versions of cpio before 2.13, input files are not properly validated when generating TAR archives. When cpio is used to create TAR archives from paths that attackers can access, the resulting archive may contain files with permissions that the attacker does not have, or in paths to which t...

Astra Linux – Vulnerability in Linux

A heap out-of-bounds write that affects Linux since v2.6.19-rc1 was discovered in net/netfilter/xtables.c. This vulnerability allows an attacker to gain privileges or cause a Denial-of-Service attack through heap memory corruption by manipulating the user name space...

Astra Linux – Vulnerability in Linux

A use-after-free flaw was discovered in cgroup1parseparam in kernel/cgroup/cgroup-v1.c within the Linux kernel’s cgroup v1 parser. A local attacker with user privileges could exploit the fsconfig syscall parameter to escalate privileges, resulting in a container breakout and a denial of service o...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A issue was discovered in the Linux kernel through version 5.18.9. A type confusion bug in nftseteleminit could be exploited by a local attacker to escalate privileges. This is a different vulnerability than CVE-2022-32250. The attacker can obtain root access, but must start with an unprivileged...

Astra Linux – Vulnerability in Linux 5.10

A flaw was discovered in the way the “flags” member of the new pipe buffer structure lacked proper initialization in the copypagetoiterpipe and pushpipe functions of the Linux kernel. As a result, these members could contain stale values. An unprivileged local user could exploit this flaw to writ...
