CVE-2026-6695
Gimp: gimp: remote code execution via crafted paa file
A flaw was found in GIMP. A remote attacker could exploit this by tricking a user into opening a specially crafted PAA (Paint Shop Pro Array) image file. This vulnerability, a heap-based out-of-bounds write in the decode_lzss() function of the PAA file format plugin, allows data to be written beyond the intended memory buffer. This could lead to heap metadata corruption and potentially enable the attacker to execute arbitrary code on the affected system.
Fixes and workarounds
Workaround
To mitigate this issue, users should avoid opening .paa files from untrusted sources. If GIMP is not required, consider removing the `gimp` package to eliminate the attack vector. Removing the `gimp` package may also remove other desktop-related packages that depend on it.
