USN-2943-1: PCRE vulnerabilities

Releases

• Ubuntu 15.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• 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

• libpcre3 - 1:8.31-2ubuntu2.2

Ubuntu 12.04

• 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.
