The NS_SecurityCompareURIs function in netwerk/base/public/nsNetUtil.h in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, does not properly handle (1) about:neterror and (2) about:certerror pages, which allows remote attackers to spoof the location bar via a crafted web site.

Security readout for executives and security teams

This is an old Mozilla browser flaw that could let a malicious website make the address bar appear to show a trusted error page location. The main business risk is user deception and phishing, not direct system takeover. Exposure is mainly legacy Firefox or SeaMonkey installations that missed the 2010 fixes. Likely limited to obsolete browser versions or legacy systems carrying old distro packages. Modern supported Firefox and SeaMonkey builds should not be exposed based on the fixed-version information in the CVE record. Treat as a legacy hygiene issue unless old browsers remain in production. Prioritize remediation on kiosks, jump hosts, shared workstations, and unsupported operating systems where users may browse the web. Mitigation focus: Upgrade Firefox to 3.5.16, 3.6.13, or a later supported release.; Upgrade SeaMonkey to 2.0.11 or a later supported release.; Apply relevant Linux distribution security updates from vendor advisories..
