Integer overflow in the makefiltertable function in pixops/pixops.c in gdk-pixbuf before 2.31.5, as used in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 on Linux, Google Chrome on Linux, and other products, allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow and application crash) via crafted bitmap dimensions that are mishandled during scaling.

io-tga.c in gdk-pixbuf before 2.32.0 uses heap memory after its allocation failed, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) and possibly execute arbitrary code via a crafted Truevision TGA (TARGA) file.
