Astra Linux – Vulnerability in git-lfs

Git LFS is an extension of Git for versioning large files. When Git LFS requests credentials from Git for a remote host, it passes portions of the host’s URL to the git-credential1 command without checking for embedded line-ending control characters. It then sends any credentials it receives back...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: x86/kprobes: Updates the kcb status flag after single-stepping. The kprobes function is fixed to update the kcb kprobes control block status flag to KPROBEHITSSDONE, even if the kp-posthandler is not set. This bug may cause a...

Astra Linux – Vulnerability in HAPProxy

There is an integer overflow in HAProxy versions 2.0 to 2.5, specifically in the htxaddheader function, which can be exploited to perform an HTTP request smuggling attack. This allows an attacker to bypass all configured http-request HAProxy Access Control Lists and possibly other access control...

In the Linux kernel, the following vulnerability has been resolved: SCTP: Fixed a memory leak in sctpstreamoutqmigrate. When sctpstreamoutqmigrate is called to release resources related to streamouts, the memory pointed to by priohead in the streamout context is not released properly. The details...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. In Redis 7.0, before version 7.0.12, extracting key names from a command and a list of arguments could, in some cases, trigger a heap overflow, leading to the reading of random heap memory, heap corruption, and potentially remote code...

Astra Linux – Vulnerability in HAPProxy

Before version 2.7.3, HAProxy might allow a bypass of access control mechanisms, as HTTP/1 headers were inadvertently lost in certain situations, also known as “request smuggling.” The HTTP header parsers in HAProxy might accept empty header field names, which could be used to omit the list of HT...
