FAUCET Score

CVE-2012-1126 describes a critical vulnerability in FreeType before version 2.4.9, impacting products like Mozilla Firefox Mobile. This flaw allows remote attackers to trigger a denial of service or potentially execute arbitrary code through specially crafted BDF font property data. With a CVSS score of 10.0, it represents a severe risk due to its network-based attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
