Published: Oct 1, 2020

PUBLISHED

Description

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. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.

Vendor	Product	Versions
Mozilla	Firefox ESR	affected `unspecified - < 68.12`
Mozilla	Thunderbird	affected `unspecified - < 68.12`
