What is CVE-2015-8387?

A critical flaw in the PCRE library prior to version 8.38 allows remote attackers to exploit improper handling of subroutine calls within regular expressions. This vulnerability can lead to a denial of service through integer overflow, potentially allowing attackers to disrupt application functionality. Notably, the issue can be triggered by crafted regular expression inputs, as demonstrated in situations like the JavaScript RegExp object in the Konqueror browser. Keeping your PCRE library updated is essential to mitigate this risk.
