Mesa 23.0.4 was discovered to contain a NULL pointer dereference in checkxshm() for the haserror state. NOTE: this is disputed because there is no scenario in which the vulnerability was demonstrated.

An Out-of-bounds memory read / write flaw was found in Mesa. A remote attacker could use this flaw to crash an application linked against or, potentially, execute arbitrary code via an application linked against Mesa graphics libraries.

Mesa v23.0.4 was discovered to contain a NULL pointer dereference via the function dri2GetGlxDrawableFromXDrawableId(). This vulnerability is triggered when the X11 server sends an DRI2BufferSwapComplete event unexpectedly when the application is using DRI3. NOTE: this is disputed because there is no scenario in which the vulnerability was demonstrated.

Mesa 23.0.4 was discovered to contain a buffer over-read in glXQueryServerString(). NOTE: this is disputed because there are no common situations in which users require uninterrupted operation with an attacker-controller server.

glxpbuffer.c in Mesa 23.0.4 was discovered to contain a segmentation violation when calling glXGetDrawableAttribute(). NOTE: this is disputed because there are no common situations in which users require uninterrupted operation with an attacker-controller server.
