CVE-2015-8385: Oracle Linux

High severity, CVSS 7.5. EPSS: 5.6% chance of exploitation in the next 30 days.

PCRE before 8.38 mishandles the /(?|(\k'Pm')|(?'Pm'))/ pattern and related patterns with certain forward references, which allows remote attackers to cause a denial of service (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

• Oracle Linux: version 7 only
• Pcre Perl Compatible Regular Expression Library: up to and including 8.37
