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

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: Fixed a kernel panic that occurs when the host sends an invalid H2C PDU length. If the host sends an H2CData command with an invalid DATAL value, the kernel may crash in the nvmettcpbuildpduiovec function. The...

Astra Linux – Vulnerability in Qemu

QEMU prior to version 8.2.0 has an integer underflow issue, which can lead to a buffer overflow. This occurs due to a TI command, where a transfer length that is not a DMA transfer is processed, and the actual transfer length is shorter than the length of the available FIFO data. This issue arise...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net/sched: flower: Fix chain template offload When a qdisc is deleted from a net device, the stack instructs the underlying driver to remove its flow offload callback from the associated filter block using the ‘FLOWBLOCKUNBIND’...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fixed the use-after-free bug. This bug can be triggered by sending a single amdgpugemuserptrioctl command to the AMDGPU DRM driver on any ASICs with an invalid address and size. The bug was reported by Joonkyo Jung...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dm: Fixed unconditional IO throttling caused by REQPREFLUSH When a bio with REQPREFLUSH is submitted to dm, sendemptyflush generates a flushbio with REQOPWRITE | REQPREFLUSH | REQSYNC, which causes the flushbio to be throttled by...

Astra Linux – Vulnerability in xrdp

xrdp is an open-source RDP server. Versions up to 0.10.5 contain a heap-based buffer overflow vulnerability in the NeutrinoRDP module. When proxying RDP sessions from xrdp to another server, the module fails to properly validate the size of reassembled fragmented virtual channel data against its...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: io-wq: Fixed a memory leak during worker creation. If the CPU mask allocation for a node fails, the memory allocated for the iowqe structure of the current node does not get freed during error handling, since it has not yet been...

Astra Linux – Vulnerability in Qemu

A use-after-free vulnerability was discovered in the am53c974 SCSI host bus adapter emulation in QEMU in versions prior to 6.0.0, during the handling of the ‘Information Transfer’ command CMDTI. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: USB: usbtmc: Use usbbulkmsgkillable with user-specified timeouts. The usbtmc driver accepts timeout values specified by the user in an ioctl command, and uses these timeouts for certain usbbulkmsg calls. Since the user can specif...

Astra Linux – Vulnerability in exiv2

Exiv2 is a C++ library and a command-line utility for reading, writing, deleting, and modifying image metadata in formats such as Exif, IPTC, XMP, and ICC. Prior to version 0.28.8, a buffer overflow vulnerability was discovered in Exiv2. The vulnerability lies in the preview component, which only...

Astra Linux – Vulnerability in Vim

Vim is an open-source, command-line text editor. Prior to version 9.2.0073, there was a vulnerability related to OS command injection in the netrw standard plugin bundled with Vim. By forcing a user to open a specially crafted URL e.g., using the scp:// protocol handler, an attacker could execute...

Astra Linux – Vulnerability in freeipmi

In FreeIPMI, the ipmi-oem command before version 1.6.17 has exploitable buffer overflows in the response messages. The Intelligent Platform Management Interface IPMI specification defines a set of interfaces for platform management. This specification is implemented by a large number of hardware...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: Initializing the event handler for read bytes A value of 0xff was set for I2C reads of the mctp-i2c device. Otherwise, reads will return “val” from the I2C bus driver. For I2c-aspeed and i2c-npcm7xx, this represents an...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in gnutls. When validating certificates, an excessively large Subject Alternative Name SAN could cause the validation process to incorrectly revert to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially...

Astra Linux – Vulnerability in hplip

A potential security vulnerability has been identified in the HP Linux Imaging and Printing Software. This vulnerability may allow for escalation of privileges and/or execution of arbitrary code through operating system command injection...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP – Fixed issue where multiple L2CAPECREDCONNREQUESTs were accepted. Currently, the code attempts to accept requests regardless of the command identifier. This can result in multiple requests being marked as pendin...

Astra Linux – Vulnerability in dovecot

Sending the “NOOP ...” command with 4000 opening and closing parentheses results in an additional 1MB of memory usage. Longer commands will cause the client to disconnect. This 1MB of memory can be reserved for longer periods of time by not sending the command that ends with LF. Thus, an attacker...

Astra Linux – Vulnerability in dovecot

The ManageSieve AUTHENTICATE command crashes when using “literal” as the initial response to SASL. This can be used to repeatedly crash the ManageSieve service, rendering it unavailable to other users. It’s recommended to control access to the ManageSieve port or disable the service if it’s not...

Astra Linux – Vulnerability in jq

jq is a command-line JSON processor. Prior to version 1.8.2, jq --rawfile could cause an invalid-state reuse and a real heap-out-of-bounds write in environments with assertion-disabled features. When jvloadfileraw=1 reads a file controlled by an attacker, it repeatedly appends file chunks to the...

Astra Linux – Vulnerability in Python 3.11, Python 3.7

The imaplib module, when a user-controlled command is passed to it, can have additional commands injected using newlines. Mitigation rejects commands that contain control characters...
