Description

A flaw was found in GIMP. An integer overflow vulnerability exists when processing ICO image files, specifically in the `ico_read_info` and `ico_read_icon` functions. This issue arises because a size calculation for image buffers can wrap around due to a 32-bit integer evaluation, allowing oversized image headers to bypass security checks. A remote attacker could exploit this by providing a specially crafted ICO file, leading to a buffer overflow and memory corruption, which may result in an application level denial of service.

• 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.
