Detailsinfo

A vulnerability was found in python-pillow Pillow up to 12.2.x. It has been rated as problematic. Affected by this issue is an unknown function of the component TGA RLE Encoder. The manipulation of the argument buffer with an unknown input leads to a heap-based overflow vulnerability. Using CWE to declare the problem leads to CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). Impacted is confidentiality. CVE summarizes:

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-59198 since 07/02/2026. The exploitation is known to be easy. Local access is required to approach this attack.
