CVE-2005-2871 describes a buffer overflow vulnerability in Mozilla Firefox versions 1.0.6 and earlier, and Netscape 7.2 and 8.0.3.3. This flaw, stemming from improper handling of "soft" hyphens (0xAD) in hostnames by the NormalizeIDN call, allows remote attackers to trigger a denial of service or potentially execute arbitrary code. With a CVSS score of 7.5, it is a high-severity vulnerability that can be exploited remotely with low attack complexity, leading to potential confidentiality, integrity, and availability impacts. While not listed in CISA's KEV catalog, an ExploitDB entry (EDB-1224) confirms the existence of exploit code, despite a lack of broader community discussion or media coverage.
