Amazon Linux AMI : xorg-x11-server (ALAS-2024-1928)

It is, therefore, affected by a vulnerability as referenced in the ALAS-2024-1928 advisory. The ProcRenderAddGlyphs function calls the AllocateGlyph function to store new glyphs sent by the client to the X server. AllocateGlyph would return a new glyph with refcount=0 and a re-used glyph would en...

Amazon Linux 2023 : xorg-x11-server-common, xorg-x11-server-devel, xorg-x11-server-source (ALAS2023-2024-583)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-583 advisory. A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents function. This issue occurs when byte-swapped length values are used in replies, potentially...

Important: xorg-x11-server
