The latest variant of the popular email client, Thunderbird 9, fixes one critical and five moderate security flaws which in certain conditions could allow a hacker to take advantage of them and compromise a computer.
According to the security
advisory that came with the new release, an issue due to which the application crashed when a video was scaled to extreme sizes was resolved.
Miscellaneous memory safety hazards, a key detection issue without JavaScript via SVG animation, an SVGValue out-of-bounds access, and a potentially exploitable crash in the YARR regular expression library were also fixed.
Unlike in the case of
Firefox, these vulnerabilities could have been taken advantage of only in uncommon non-default configurations that required the user to perform some unlikely procedures.
Users are advised to update Thunderbird to the latest version to make sure they’re protected against potential attacks.
