Name of the Vulnerable Software and Affected Versions PCRE versions prior to 8.38

Description The issue is related to the mishandling of certain conditions in regular expressions, which can be exploited by remote attackers to cause a denial of service due to an integer overflow. This can be achieved by crafting a specific regular expression. The impact of this issue may also extend beyond a denial of service, although the specifics are not detailed.

Recommendations For versions prior to 8.38, update to version 8.38 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted regular expressions that could trigger the integer overflow until a patch is applied. Avoid using the RegExp object with untrusted input in JavaScript until the issue is resolved.
