USN-948-1: GnuTLS vulnerability
3 June 2010
Under certain circumstances, an attacker might be able to crash GnuTLS.
Releases
Packages
- gnutls12 - the GNU TLS library
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 6.06
In general, a standard system update will make all the necessary changes.
