GIMP HDR 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 HDR 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-28266.

A flaw was found in GIMP. This vulnerability, a heap-based buffer overflow, occurs during the parsing of HDR (High Dynamic Range) files due to insufficient validation of user-supplied data length. A remote attacker could exploit this by convincing a user to open a specially crafted malicious file, leading to arbitrary code execution within the context of the current process.

This Important vulnerability in GIMP allows for arbitrary code execution through a heap-based buffer overflow during HDR file parsing. Successful exploitation requires user interaction, where an attacker must persuade a user to open a malicious file. This prerequisite reduces the immediate threat compared to remote, unauthenticated flaws, but the potential for system compromise warrants an Important rating. Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
