Doc Text:
A flaw was found in GIMP. This stack-based buffer overflow vulnerability occurs during the parsing of LBM files due to insufficient validation of user-supplied data length. A remote attacker can exploit this by tricking a user into opening a specially crafted malicious LBM file. Successful exploitation could lead to arbitrary code execution in the context of the current process.

Description OSIDB Bzimport 2025-12-23 22:06:52 UTC
GIMP LBM File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of LBM files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28311.
