CVE-2007-0778: The page cache feature in Mozilla Firefox before 1.5.0.10 and 2.x before 2.0.0.2, and SeaMonkey before 1.0....

Security readout for executives and security teams

This old Mozilla browser flaw could mix cached page data between pages. A malicious remote site might cause sensitive information from one cached page to appear in another context when the target page reloads. The affected products are legacy Firefox and SeaMonkey versions from 2007. Modern environments are unlikely to be exposed unless they run obsolete Firefox or SeaMonkey builds, embedded legacy browsers, or old Linux/Unix packages. Confirm through software inventory rather than assuming the issue is absent. Treat this as a legacy exposure cleanup item. It does not justify emergency action without affected obsolete browsers, but any confirmed instance should be removed or updated because browser information disclosure can affect sensitive sessions. Mitigation focus: Upgrade Firefox to 1.5.0.10, 2.0.0.2, or later supported vendor packages.; Upgrade SeaMonkey to 1.0.8 or later supported vendor packages.; Apply relevant OS vendor updates from Red Hat, Gentoo, Debian, Ubuntu, Slackware, or HP..
