GEGL PPM image handler buffer overflow
|gegl-ppm-bo (79822)||High Risk|
GEGL is vulnerable to a heap-based buffer overflow, caused by an integer overflow in PPM image handler. By using specially-crafted image dimensions, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Apply the patch for this vulnerability, available from the GEGL Repository. See References.
