NVD Description

Note: Versions mentioned in the description apply only to the upstream MozillaFirefox-branding-SLE package and not the MozillaFirefox-branding-SLE package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

When the Mozilla Updater opens a MAR format file which contains a very long item filename, an out-of-bounds write can be triggered, leading to a potentially exploitable crash. This requires running the Mozilla Updater manually on the local system with the malicious MAR file in order to occur. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1.
