CVE-2023-4578, medium severity (CVSS 6.5): 2 tracked apps concerned, all fixed or indeterminable on their current version.

Severity (CVSS): 6.5
Exploitation: 0.6 %
Tracked apps: 2
Still exposed: 0

Published on 2023-09-11

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.
