MGASA-2022-0097 - Updated thunderbird packages fix security vulnerabilities

Publication date: 11 Mar 2022
URL: https://advisories.mageia.org/MGASA-2022-0097.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-26381,
     CVE-2022-26383,
     CVE-2022-26384,
     CVE-2022-26386,
     CVE-2022-26387

An attacker could have caused a use-after-free by forcing a text reflow in an
SVG object leading to a potentially exploitable crash (CVE-2022-26381).

When resizing a popup after requesting fullscreen access, the popup would not
display the fullscreen notification (CVE-2022-26383).

If an attacker could control the contents of an iframe sandboxed with
allow-popups but not allow-scripts, they were able to craft a link that, when
clicked, would lead to JavaScript execution in violation of the sandbox
(CVE-2022-26384).

Previously Thunderbird for macOS and Linux would download temporary files to
a user-specific directory in /tmp, but this behavior was changed to download
them to /tmp where they could be affected by other local users. This behavior
was reverted to the original, user-specific directory (CVE-2022-26386).

When installing an add-on, Thunderbird verified the signature before
prompting the user; but while the user was confirming the prompt, the
underlying add-on file could have been modified and Thunderbird would not
have noticed (CVE-2022-26387).
