3Description
GIMP ICNS 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 ICNS 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-28530.
Analysis
Remote code execution in GIMP through heap buffer overflow during ICNS file parsing allows attackers to execute arbitrary code when a user opens a malicious image file. The vulnerability stems from insufficient validation of user-supplied data lengths before copying to heap memory, requiring only user interaction to trigger. …
