An integer overflow vulnerability exists in the Compound Document Binary File format parser of v1.14.52 of the GNOME Project G Structured File Library (libgsf). A specially crafted file can result in an integer overflow that allows for a heap-based buffer overflow when processing the sector allocation table. This can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
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.
