Doc Text:	A remote code execution vulnerability exists in GIMP due to improper validation of user-supplied data during the parsing of WBMP (Wireless Bitmap) files. The flaw occurs because an integer overflow can happen before memory allocation, leading to a heap-based buffer overflow. An attacker can exploit this by convincing a user to open a crafted WBMP image file or visit a malicious page, allowing arbitrary code execution within the context of the application process.

Description OSIDB Bzimport 2025-10-29 20:01:55 UTC

GIMP WBMP 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 WBMP 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-27878.
