Description
GIMP ANI File Parsing Integer 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 ANI files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28813.
Analysis
Remote code execution in GIMP via integer overflow during ANI (animated cursor) file parsing allows unauthenticated attackers to execute arbitrary code with user privileges when malicious ANI files are opened. Exploitation requires user interaction (opening crafted file or visiting attacker-controlled page). …
