Sicherheitslücken in libxpm

Denial of service via unsigned underflow in libXpm's write path

A denial of service via unsigned underflow in libXpm's write path in libXpm before 3.5.19 could be used by local attackers to cause unbounded CPU usage and memory exhaustion.

Libxpm: libxpm: denial of service via out-of-bounds read in xpm file parsing

A flaw was found in libXpm. A local user with low privileges could exploit an Out-of-Bounds Read vulnerability in the `xpmNextWord()` function by processing a specially crafted or very small XPM (X PixMap) image file. This improper validation of file boundaries can cause an internal pointer to read beyond the file's end, leading to application crashes and Denial of Service conditions.

Libxpm: out of bounds read on xpm with corrupted colormap

A vulnerability was found in libXpm where a vulnerability exists due to a boundary condition, a local user can trigger an out-of-bounds read error and read contents of memory on the system.

Libxpm: out of bounds read in xpmcreatexpmimagefrombuffer()

A vulnerability was found in libXpm due to a boundary condition within the XpmCreateXpmImageFromBuffer() function. This flaw allows a local attacker to trigger an out-of-bounds read error and read the contents of memory on the system.

Libx11: integer overflow in xcreateimage() leading to a heap overflow

A vulnerability was found in libX11 due to an integer overflow within the XCreateImage() function. This flaw allows a local user to trigger an integer overflow and execute arbitrary code with elevated privileges.

Libx11: stack exhaustion from infinite recursion in putsubimage()

A vulnerability was found in libX11 due to an infinite loop within the PutSubImage() function. This flaw allows a local user to consume all available system resources and cause a denial of service condition.
