Description

Integer overflow in io-ico.c in gdk-pixbuf allows context-dependent attackers to cause a denial of service (segmentation fault and application crash) via a crafted image entry offset in an ICO file, which triggers an out-of-bounds read, related to compiler optimizations.

• CWE-190Integer Overflow or WraparoundThe 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.
