Integer overflow in plug-ins/common/psd.c in the Adobe Photoshop PSD plugin in GIMP 2.2.13 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted channels header value in a PSD image file, which triggers a heap-based buffer overflow, a different vulnerability than CVE-2009-3909.
The product 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 occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
