Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS

Summary:

PCRE could be made to crash or run programs if it processed a specially-crafted regular expression.

Software Description: - pcre3: Perl 5 Compatible Regular Expression Library

Details:

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.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.10:
libpcre3 2:8.35-7.1ubuntu1.3

Ubuntu 14.04 LTS:
libpcre3 1:8.31-2ubuntu2.2

Ubuntu 12.04 LTS:
libpcre3 8.12-4ubuntu0.2

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.
