In the Linux kernel, the following vulnerability has been resolved: fs/proc: dotaskstat: The sig-statslock lock is used to gather statistics about threads/children. The locktasksighand function can cause a hard lockup. If NRCPUS threads call dotaskstat at the same time, and the process has...

Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. When using the Redis Lua Debugger, users can send malformed requests, causing the debugger’s protocol parser to read data beyond the actual buffer. This issue affects all versions of Redis with Lua debugging support 3.2 or...

Astra Linux – Vulnerability in Linux 5.10

There is a flaw in the Linux kernel’s handling of new TCP connections. The issue arises due to the lack of memory release after the effective lifetime of these connections. This vulnerability allows an unauthenticated attacker to create a denial-of-service condition on the system...

Astra Linux – Vulnerability in Linux, Linux 5.10

A heap-based buffer overflow flaw was discovered in the way the legacyparseparam function in the Linux kernel’s Filesystem Context functionality verifies the length of the supplied parameters. A non-privileged user if non-privileged user namespaces are enabled, otherwise requiring CAPSYSADMIN...

Astra Linux – Vulnerability in glibc

The Name Service Cache Daemon’s nscd netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. This flaw was introduced in glibc 2.15, when the cache was added to nscd. This vulnerability only exists in the nscd binary...

Astra Linux – Vulnerability in Golang-1.19

HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate significantly more memory than is...

Astra Linux – Vulnerability in TIF format

The processCropSelections function in the tools/tiffcrop.c file of LibTIFF, as of version 4.5.0, has a heap-based buffer overflow vulnerability. This vulnerability occurs due to a crafted TIFF image being written with a size of 307203 bytes...

Astra Linux – Vulnerability in emacs

GNU Emacs version 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file. This is because lib-src/etags.c uses the system’s C library function in its implementation of the ctags program. For example, a victim might use the “ctags ” command as suggeste...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: afunix: fix use-after-free in unixstreamreadactor syzbot reported the following crash 1 After releasing unix socket lock, u-oobskb can be changed by another thread. We must temporarily increase skb refcount to make sure this othe...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. Redis does not correctly identify keys accessed using SORTRO. As a result, it may grant users who execute this command access to keys that are not explicitly authorized by the ACL configuration. This issue exists in Redis 7.0 or later...

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

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetpipapo: release elements in clone only from destroy path The clone function always provides a current view of the lookup table; use this to destroy the set. Otherwise, it is possible to destroy elements twice. Th...

Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in the udmabuf device driver of the Linux kernel. The specific flaw resides within a fault handler. The issue arises due to the lack of proper validation of user-supplied data, which can lead to a memory access beyond the end of an array. An attacker can exploit this...

Astra Linux – Vulnerability in Linux 5.10

A out-of-bounds memory write flaw was discovered in the Linux kernel’s watchqueue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system...

Astra Linux – Vulnerability in glibc

nscd: Null pointer crash after a “notfound” response If the Name Service Cache Daemon’s nscd cache fails to add a “notfound” netgroup response to its cache, the client request may lead to a null pointer dereferencing. This flaw was introduced in glibc 2.15 when the cache was moved to nscd. This...

Astra Linux – Vulnerability in unbound, bind9

The “Closest Encloser Proof” aspect of the DNS protocol as described in RFC 5155, when the guidance provided in RFC 9276 is skipped enables remote attackers to cause a denial of service resulting in high CPU usage for SHA-1 calculations through DNSSEC responses during a random subdomain attack,...

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

A denial-of-service issue was detected, possibly due to a recursive locking scenario, which led to a deadlock in the tableclear function in drivers/md/dm-ioctl.c within the Linux Kernel Device Mapper-Multipathing sub-component...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x8664 lacks consistency checks for CR0 and CR4...

Astra Linux – Vulnerability in Firefox and Thunderbird

Mozilla developers Nika Layzell, Timothy Nikkel, Sebastian Hengst, Andreas Pehrson, and the Mozilla Fuzzing Team reported memory safety bugs in Firefox 104 and Firefox ESR 102.2. Some of these bugs exhibited signs of memory corruption, and we assume that with sufficient effort, some of these bugs...

Astra Linux – Vulnerability in Firefox

Mozilla developers Timothy Nikkel, Ashley Hale, and the Mozilla Fuzzing Team reported memory safety bugs in Firefox 105. Some of these bugs exhibited signs of memory corruption, and we assume that with sufficient effort, some of these bugs could have been exploited to execute arbitrary code. This...

Astra Linux – Vulnerability in tar

GNU Tar version 1.34 has a one-byte out-of-bounds read operation, which allows for the use of uninitialized memory in a conditional jump. Exploitation to change the control flow of the program has not been demonstrated. The issue occurs in the fromheader section of the list.c file, due to a V7...
