Astra Linux – Vulnerability in grub2

The “read” command is used to read the keyboard input from the user. While reading, the input length is stored as a 32-bit integer value. This value is then used to reallocate the line buffer to accommodate the next character. During this process, if the line is long enough, it’s possible for thi...

Astra Linux – Vulnerability in qt4-x11, qtbase-opensource-src

In Qt versions prior to 5.15.15, 6.x before 6.2.9, and 6.3.x through 6.5.x before 6.5.2, there may be an application crash in QXmlStreamReader due to a crafted XML string, causing a situation where a prefix is greater than a certain length...

Astra Linux – Vulnerability in rsync

In rsync versions 3.0.1 through 3.4.1, the receivexattr function relies on an untrusted length value during a qsort call, resulting in a use-after-free vulnerability. The vulnerability is exploitable when rsync is executed with the -X option also known as --xattrs. On Linux, many but not all comm...
