CVE-2005-2267: Firefox before 1.0.5 allows remote attackers to steal information and possibly execute arbitrary code by us...

Security readout for executives and security teams

This is an old Firefox flaw where external media applications could cause script to run in the wrong browser context. On vulnerable Firefox versions before 1.0.5, that could expose page data and possibly lead to code execution in limited circumstances. Exposure is most likely in legacy systems still running Firefox before 1.0.5 or old vendor-packaged browser builds. Current managed desktop fleets should only be affected if obsolete browsers remain installed for compatibility or archival use. Treat this as a legacy exposure cleanup item unless old Firefox deployments are present. If vulnerable browsers remain, prioritize removal because the issue can cross browser context boundaries and may allow sensitive data theft. Mitigation focus: Upgrade Firefox to 1.0.5 or later where applicable.; Remove obsolete Firefox builds from managed endpoints.; Check Mozilla and Linux vendor advisories for package-specific fixes..
