CVE-2014-9769 PCRE vulnerabilities
Title: PCRE vulnerabilities
Summary: PCRE could be made to crash or run programs if it processed a
specially-crafted regular expression.
It was discovered that PCRE incorrectly handled certain regular
expressions. A remote attacker could use this issue to cause applications
using PCRE to crash, resulting in a denial of service, or possibly execute
arbitrary code.
Instructions: After a standard system update you need to restart applications using PCRE,
such as the Apache HTTP server and Nginx, to make all the necessary
changes.
