USN-151-1: zlib vulnerability

Releases

• Ubuntu 5.04
• Ubuntu 4.10

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 5.04

• zlib1g -

Ubuntu 4.10

• zlib1g -

In general, a standard system update will make all the necessary changes.
