Integer Overflow or Wraparound
Multiple integer overflows in the load_image function in file-pcx.c in the Personal Computer Exchange (PCX) plugin in GIMP 2.6.x and earlier allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PCX image that triggers a heap-based buffer overflow.
CWE-190 - Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.
