Debian DLA-1918-1 : libonig security update

high Nessus Plugin ID 128778

Language:

Synopsis

The remote Debian host is missing a security update.

Description

The Oniguruma regular expressions library, notably used in PHP mbstring, is vulnerable to stack exhaustion. A crafted regular expression can crash the process.

For Debian 8 'Jessie', this problem has been fixed in version 5.9.5-3.2+deb8u3.

We recommend that you upgrade your libonig packages.

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

Solution

Upgrade the affected libonig-dev, libonig2, and libonig2-dbg packages.
