CWE-119Published: November 2, 2007· Updated: Jun 16, 2026
7.5
CVSS v3.1
Official Description
Buffer overflow in the Mono.Math.BigInteger class in Mono 1.2.5.1 and earlier allows context-dependent attackers to execute arbitrary code via unspecified vectors related to Reduce in Montgomery-based Pow methods.
Technical Analysis
CVE-2007-5197 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
