Red Hat: CVE-2025-10923: gimp: GIMP WBMP File Parsing Integer Overflow Remote Code Execution Vulnerability (Multiple Advisories)

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.
