MGASA-2020-0352 - Updated thunderbird packages fix security vulnerabilities

Publication date: 28 Aug 2020
URL: https://advisories.mageia.org/MGASA-2020-0352.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-15664,
     CVE-2020-15669

Description:
By holding a reference to the eval() function from an about:blank window, a
malicious webpage could have gained access to the InstallTrigger object which
would allow them to prompt the user to install an extension. Combined with user
confusion, this could result in an unintended or malicious extension being
installed (CVE-2020-15664).

When aborting an operation, such as a fetch, an abort signal may be deleted
while alerting the objects to be notified. This results in a use-after-free and
we presume that with enough effort it could have been exploited to run
arbitrary code (CVE-2020-15669).
