Integer Overflow in libgsf 1.14.52 (GNOME) leading to heap Bof
CVE-2024-42415 Published on October 3, 2024
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.
Vulnerability Analysis
CVE-2024-42415 can be exploited with local system access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. Public availability of a proof of concept (POC) exploit exists for CVE-2024-42415. The potential impact of an exploit of this vulnerability is considered to be very high.
Weakness Type
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. An integer overflow or wraparound 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 wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.
