A flaw was found in GIMP. A stack buffer overflow vulnerability in the TIM image loader's 4BPP decoding path allows a local user to cause a Denial of Service (DoS). By opening a specially crafted TIM image file, the application crashes due to an unconditional overflow when writing to a variable-length array.
To mitigate this issue, users should avoid opening untrusted TIM image files with GIMP. As a general security practice, users should exercise caution when handling files from unknown or suspicious sources.
