Firefox 5 update for Mac users could have security links, says Sophos

Mozilla's update to Firefox 5 for Mac users, version 5.0.1, aimed at eliminating crashes when using a downloadable font in OS X 10.7 and fixing the Java plug-in in OS X 10.5, could have security links, says Sophos.

Although the update is not really a security fix, crashes, such as the OS X font problem in OS X 10.7, always imply some security risk, said Paul Ducklin, Sophos head of technology, Asia Pacific.

"Whenever a program takes an uncharted and unexpected path of execution, there is cause for concern," he wrote in a blog post.

Ducklin said it is good to see that Mozilla is willing to produce this sort "between-the-train-stations" release, despite the fact that version 6 is due relatively soon in mid-August.
