GIMP JP2 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 JP2 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-28863.
Analysis
Heap-based buffer overflow in GIMP's JP2 image parser enables unauthenticated remote code execution when users open crafted JPEG 2000 files. The vulnerability stems from insufficient validation of user-supplied data length before copying to heap memory, allowing attackers to execute arbitrary code with user privileges. …
