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.
