Mozilla issued an update on Wednesday to address several vulnerabilities with older, but still widely used, versions of its web browser that create a possible means for hackers to attack vulnerable PCs.
Related flaws also prompted an update to the SeaMonkey application suite.
Users are advised to upgrade to Mozilla Firefox 188.8.131.52 and SeaMonkey 1.0.6 in order to address scripting errors and memory corruption security bugs that could be used in cross site scripting, denial of service or remote access attacks. The flaws do not apply to Firefox 2.0, the latest version of Mozilla's browser software, which was released in late October.
Security notification service Secunia has published an advisory giving an overview on the bugs.
