Ubuntu 4.10 / 5.04 : zlib vulnerability (USN-151-1)

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN-148-1 fixed an improver input verification of zlib
(CAN-2005-2096). Markus Oberhumer discovered additional ways a
disrupted stream could trigger a buffer overflow and crash the
application using zlib, so another update is necessary.

zlib is used by hundreds of server and client applications, so this
vulnerability could be exploited to cause Denial of Service attacks to
almost all services provided by an Ubuntu system.

Solution :

Update the affected zlib-bin, zlib1g and / or zlib1g-dev packages.

Risk factor :

High / CVSS Base Score : 7.5
