GIMP is vulnerable to a heap-based buffer overflow due to improper validation of TIF file lengths, allowing remote attackers to execute arbitrary code when a user interacts with a malicious file or webpage. This high-severity vulnerability poses a significant risk, particularly for users who frequently handle TIF files or access untrusted sources. Organizations using GIMP should prioritize patching this vulnerability to mitigate potential exploitation.

Original NVD Description

GIMP TIF File Parsing Heap-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 TIF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29404.
