Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. In affected versions, a integer overflow bug in Redis can be exploited to corrupt the heap and potentially lead to remote code execution. The vulnerability involves changing the default proto-max-bulk-len and...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: i40e: Fixed the call trace in setuptxdescriptors. After a PF reset and the use of ethtool -t, there was a call trace in dmesg. Sometimes this led to a panic. After some time, approximately 5 seconds, between a reset and a test...

Astra Linux – Vulnerability in exiv2

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An inefficient algorithm quadratic complexity was found in Exiv2 versions v0.27.3 and earlier. This inefficient algorithm occurs when Exiv2 is used to write metadata into a...

Astra Linux – Vulnerability in liblivemedia

In Live Networks, Inc., liblivemedia version 20200625, there is a potential buffer overflow bug in the server’s handling of the RTSP “PLAY” command, especially when the command specifies seeking by absolute time...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fixed a race condition between searching chunks and releasing the journalhead from the bufferhead. A race condition was encountered between ocfs2testbgbitallocatable and jbd2journalputjournalhead, resulting in the followin...

Astra Linux – Vulnerability in Linux 5.15

A issue was discovered in the net/ceph/messengerv2.c file within the Linux kernel before version 6.4.5. There is an integer signedness error, which leads to a buffer overflow and remote code execution via the HELLO command or one of the AUTH frames. This occurs due to an untrusted length value...

Astra Linux – Vulnerability in jq

jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed 0x432A9843 for all JSON object hash table operations. This allowed attackers to precompute key collisions offline. By providing a crafted JSON...

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

In the Linux kernel, the following vulnerabilities have been resolved: firmwareloader: Block path traversal Most firmware names are hardcoded strings, or are constructed from fairly constrained format strings where the dynamic parts are just some hexadecimal numbers or similar elements. However,...

Astra Linux – Vulnerability in jq

jq is a command-line JSON processor. In commits after 69785bf77f86e2ea1b4a20ca86775916889e91c9, the strindices builtin function in jq’s src/builtin.c passes its arguments directly to jvstringindexes, without verifying that they are strings. Additionally, jvstringindexes in src/jv.c relies solely ...

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

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Added a length limitation for the ivrsacpihid command-line parameter. The acpiid buffer in the parseivrsacpihid function may overflow, because the string specifier in the fscan function lacks a width limitation. Found ...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: uprobe: avoided out-of-bounds memory access when fetching args Uprobe needs to fetch args into a percpu buffer, and then copy them to the ring buffer to avoid non-atomic context problems. Sometimes user-space strings or arrays ca...

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

In the Linux kernel, the following vulnerability has been resolved: IB/ipoib: Fixed the issue with locking the mcast list. The release of priv-lock while iterating over priv-multicastlist in ipoibmcastjointask creates a situation where ipoibmcastdevFlush may remove the items while the iteration i...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: scsi: target: core: Fix targetcmdcounter leak The targetcmdcounter structure, which is allocated using targetalloccmdcounter, is never freed, resulting in leaks across various transport types. For example: - Unreferenced objec...
