3Description
GIMP XWD File Parsing Out-Of-Bounds Write 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 XWD files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28591.
Analysis
GIMP is vulnerable to out-of-bounds memory write during XWD file parsing due to insufficient input validation, enabling arbitrary code execution when a user opens a malicious image file. This high-severity vulnerability (CVSS 7.8) affects local attackers who can craft specially crafted XWD files to corrupt memory and execute code with the privileges of the GIMP process. …
