An integer overflow, leading to heap-based buffer overflow was found in the way portable pixmap format (PPM) image file format handler of GEGL, a graph based image processing framework, processed certain input PPM image file headers. A remote attacker could provide a specially-crafted PPM image that when opened in gegl executable would lead to crash, or, potentially arbitrary code execution with the privileges of the user running the binary.
