How to fix?

Upgrade Debian:unstable firefox-esr to version 115.2.0esr-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox-esr package and not the firefox-esr package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

When calling JS::CheckRegExpSyntax a Syntax Error could have been set which would end in calling convertToRuntimeErrorAndClear. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.
