GIMP Seattle Filmworks Loader Heap Overflow -> Arbitrary Exec
CVE-2026-59087 Published on August 10, 2026
Gimp: heap buffer overflow in `file-seattle-filmworks` load — `fread` writes attacker-controlled length into undersized allocation
A flaw was found in the GIMP image manipulation program, specifically within its Seattle Filmworks file loader. A remote attacker could exploit this vulnerability by tricking a user into opening a specially crafted Seattle Filmworks file. This could lead to a heap overflow, allowing the attacker to write several kilobytes of controlled data beyond the intended memory buffer. Such an overflow can result in memory corruption, potentially leading to arbitrary code execution or a denial of service.

Weakness Type
What is a Memory Corruption Vulnerability?
The software writes data past the end, or before the beginning, of the intended buffer. Typically, this can result in corruption of data, a crash, or code execution. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent write operation then produces undefined or unexpected results.
CVE-2026-59087 has been classified to as a Memory Corruption vulnerability or weakness.
