Astra Linux – Vulnerability in ntfs-3g

A buffer overflow was discovered in NTFS-3G before October 3, 2022. Metadata created within an NTFS image can lead to code execution. A local attacker can exploit this vulnerability if the ntfs-3g binary has the setuid root privilege. An attacker who is physically nearby can also exploit this...

Astra Linux – vulnerability in linux-5.10, linux-6.1, linux-5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - copy IV using skcipher ivsize AFALG rfc3686-ctr-aes-ccp requests pass an 8-byte IV to the driver. ccpaescomplete restores AESBLOCKSIZE bytes into the caller’s IV buffer; since RFC3686 skciphers expose an 8-byte IV,...

Astra Linux – Vulnerability in libxml-parser-perl

Versions of XML::Parser from 2.45 onwards for Perl may overflow the pre-allocated buffer size, leading to heap corruption double-free or corruption and crashes. The A:utf8 PerlIO layer, using the parsestream function in Expat.xs, may cause the XML input buffer to overflow. This is because Perl’s...

In the Linux kernel, the following vulnerability has been resolved: proc/vmcore: fix clearing user buffer by properly using clearuser To clear a user buffer, we cannot simply use memset; we must use clearuser. With a virtio-mem device that registers a vmcorecb and contains some logically unplugge...

Astra Linux – Vulnerability in Redis

Redis is an open-source, in-memory database that persists data on disk. In versions starting from 2.6 and prior to 7.4.3, an unauthenticated client can cause the output buffer to grow indefinitely, until the server runs out of memory or is terminated. By default, Redis’s configuration does not...

Astra Linux – vulnerability in linux-5.15

An issue was found in net/ceph/messengerv2.c within the Linux kernel prior to version 6.4.5. There is an integer signedness error that results in a buffer overflow, enabling remote code execution via the HELLO message or one of the AUTH frames. This occurs due to an untrusted length value extract...
