xorg-x11-server: Use-after-free in ProcRenderAddGlyphs

A use-after-free vulnerability was found in the ProcRenderAddGlyphs function of Xorg servers. This issue occurs when AllocateGlyph is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently,...

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: tigervnc

Issue Overview: 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 end up not changing the refcount at all. The resulting glyphnew array would th...
