CVE-2006-0294

22
FAUCET Score

CVE-2006-0294 is a critical memory corruption vulnerability affecting Mozilla Firefox before 1.5.0.1, Thunderbird 1.5 (when JavaScript is enabled in mail), and SeaMonkey before 1.0. This flaw allows remote attackers to execute arbitrary code by manipulating an element's style, causing the Gecko rendering engine to operate on freed memory. With a CVSS score of 7.5, it poses a significant risk, as it can be exploited remotely with low attack complexity, potentially leading to partial confidentiality, integrity, and availability compromise. While no active exploits, public exploit code, or significant community discussion have been identified, its age and the nature of the vulnerability suggest it should still be considered in legacy system assessments.
