Slackware Linux 15.0 / current mozilla-thunderbird Multiple Vulnerabilities (SSA:2022-153-01)

critical Nessus Plugin ID 161793


The remote Slackware Linux host is missing a security update to mozilla-thunderbird.


The version of mozilla-thunderbird installed on the remote host is prior to 91.10.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2022-153-01 advisory.

- Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 100 and Firefox ESR 91.9. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.

- When displaying the sender of an email, and the sender name contained the Braille Pattern Blank space character multiple times, Thunderbird would have displayed all the spaces. This could have been used by an attacker to send an email message with the attacker's digital signature, that was shown with an arbitrary sender email address chosen by the attacker. If the sender name started with a false email address, followed by many Braille space characters, the attacker's email address was not visible. Because Thunderbird compared the invisible sender address with the signature's email address, if the signing key or certificate was accepted by Thunderbird, the email was shown as having a valid digital signature. This vulnerability affects Thunderbird < 91.10. (CVE-2022-1834)

- A malicious website could have learned the size of a cross-origin resource that supported Range requests.
This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31736)

- A malicious webpage could have caused an out-of-bounds write in WebGL, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31737)

- When exiting fullscreen mode, an iframe could have confused the browser about the current state of fullscreen, resulting in potential user confusion or spoofing attacks. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31738)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Upgrade the affected mozilla-thunderbird package.
