Ubuntu Security Notice USN-948-1
3rd June, 2010
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
Under certain circumstances, an attacker might be able to crash GnuTLS.
- gnutls12 - the GNU TLS library
It was discovered that GnuTLS did not always properly verify the hash
algorithm of X.509 certificates. If an application linked against GnuTLS
processed a crafted certificate, an attacker could make GnuTLS dereference
a NULL pointer and cause a DoS via application crash.
The problem can be corrected by updating your system to the following package version:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
