critical Nessus Plugin ID 90306

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libpcre3 package.
