| Vector | AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 99
Firefox ESR versions prior to 91.8
Thunderbird versions prior to 91.8
Description
The issue is related to an error in memory release when handling links with
rel="localization". This could allow a remote attacker to execute arbitrary code by using a specially crafted web page, potentially triggering a use-after-free error by destroying an object during JavaScript execution and then referencing the object through a freed pointer, leading to a potential exploitable crash.Recommendations
For Firefox versions prior to 99, update to version 99 or later.
For Firefox ESR versions prior to 91.8, update to version 91.8 or later.
For Thunderbird versions prior to 91.8, update to version 91.8 or later.
As a temporary workaround, consider avoiding links with
rel="localization" until a patch is available.Exploit
