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.

This vulnerability is rated Important for Red Hat products as it allows for remote code execution in GIMP. Exploitation requires user interaction, specifically tricking a user into opening a specially crafted malicious LBM file.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this vulnerability, users should avoid opening untrusted LBM files with GIMP.
