Debian DLA-2085-1 : zlib security update

High Nessus Plugin ID 133323

Synopsis

The remote Debian host is missing a security update.

Description

Several issues have been found in zlib, a compression library. They are basically about improper big-endian CRC calculation, improper left shift of negative integers and improper pointer arithmetic.

For Debian 8 'Jessie', these problems have been fixed in version 1:1.2.8.dfsg-2+deb8u1.

We recommend that you upgrade your zlib 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 packages.
