A flaw was found in GIMP's Paint Shop Pro (PSP) file format parser. This heap buffer overflow vulnerability allows a remote attacker to cause arbitrary code execution or a denial of service (DoS) by tricking a user into opening a specially crafted PSP image file. The vulnerability occurs because the software incorrectly calculates buffer sizes when processing low bit-depth images, leading to an overwrite of adjacent memory.
To mitigate this vulnerability, users should avoid opening untrusted Paint Shop Pro (PSP) image files with GIMP. As a general security practice, it is recommended to only process image files from trusted sources. If GIMP is not essential, consider removing the package to eliminate the attack surface.
