The X.Org project reports:

• CVE-2024-31080: Heap buffer overread/data leakage in ProcXIGetSelectedEvents

  The ProcXIGetSelectedEvents() function uses the byte-swapped length of the return data for the amount of data to return to the client, if the client has a different endianness than the X server.

• CVE-2024-31081: Heap buffer overread/data leakage in ProcXIPassiveGrabDevice

  The ProcXIPassiveGrabDevice() function uses the byte-swapped length of the return data for the amount of data to return to the client, if the client has a different endianness than the X server.

• CVE-2024-31083: User-after-free in ProcRenderAddGlyphs

  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 glyph_new array would thus have multiple entries pointing to the same non-refcounted glyphs. ProcRenderAddGlyphs() may free a glyph, resulting in a use-after-free when the same glyph pointer is then later used.
