High

Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions PCRE versions prior to 8.36

Description The issue is related to the mishandling of certain patterns with recursion, such as the /((?(R)a|(?1)))+/ pattern, which can be exploited by remote attackers to cause a denial of service, potentially leading to a segmentation fault. This can be achieved through a crafted regular expression. For example, a JavaScript RegExp object can be used to trigger this issue, as demonstrated by its encounter with Konqueror.

Recommendations For PCRE versions prior to 8.36, update to version 8.36 or later to resolve the issue.
