CVE-2015-8380: Fedoraproject Fedora

High severity, CVSS 7.5. EPSS: 4.4% chance of exploitation in the next 30 days.

The pcre_exec function in pcre_exec.c in PCRE before 8.38 mishandles a // pattern with a \01 string, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.

Affected products

• Fedoraproject Fedora: version 22 only
• Pcre Perl Compatible Regular Expression Library: up to and including 8.37
