Astra Linux – Vulnerability in grub2

When rendering certain Unicode sequences, Grub2’s font code does not properly validate whether the width and height of the glyph are within the bitmap size. As a result, an attacker can create an input that will cause an out-of-bounds write to Grub2’s heap, leading to memory corruption and...

Astra Linux – Vulnerability in xorg-server

A use-after-free vulnerability was discovered in the ProcRenderAddGlyphs function of Xorg servers. This issue arises when the AllocateGlyph function is called to store new glyphs sent by the client to the X server. As a result, multiple entries may point to the same non-refcounted glyphs...
