Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

A heap buffer overflow vulnerability in GIMP's Paint Shop Pro file format parser may cause a denial of service by opening a specially crafted image file. The vulnerability occurs due to incorrect buffer size calculations. Affected versions are not specified.

Automatic dependency matching is unavailable for this record. Use the product evidence and publisher’s instructions to check your installation.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

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.

Original source description

Read the full publisher description

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.
