REDHAT-BUG-2520576: Integer Overflow
GIMP TIF 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 TIF 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-29405.

Frequently Asked Questions
What must an attacker do to exploit this issue?
The attacker must get a target to visit a malicious page or open a malicious TIF file. Exploitation relies on crafted user-supplied TIF data reaching GIMP's file parser.
What level of access could successful exploitation provide?
Successful exploitation can allow arbitrary code execution in the context of the current GIMP process. The resulting privileges are therefore limited to those of the user running GIMP.
How can defenders identify potentially affected activity?
Review whether users opened untrusted TIF files or visited untrusted pages that may have delivered such files. The provided information does not include affected version ranges or specific detection indicators.
