USN151-1 : zlib vulnerability

Vulnerability Assessment Summary
zlib vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- zlib-bin
- zlib1g
- zlib1g-dev

Description :

USN-148-1 fixed an improver input verification of zlib
(CVE-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 :

Upgrade to :
- zlib-bin-1.2.2-4ubuntu1.2 (Ubuntu 5.04)
- zlib1g-1.2.2-4ubuntu1.2 (Ubuntu 5.04)
- zlib1g-dev-1.2.2-4ubuntu1.2 (Ubuntu 5.04)
