Ubuntu Security Notice USN-314-1
12th July, 2006
samba vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
- Ubuntu 5.10
- Ubuntu 5.04
Details
The Samba security team reported a Denial of Service vulnerability in
the handling of information about active connections. In certain
circumstances an attacker could continually increase the memory usage
of the smbd process by issuing a large number of share connection
requests. By draining all available memory, this could be exploited to
render the remote Samba server unusable.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 6.06 LTS:
- samba 3.0.22-1ubuntu3.1
- Ubuntu 5.10:
- samba 3.0.14a-6ubuntu1.1
- Ubuntu 5.04:
- samba 3.0.10-1ubuntu3.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system upgrade is sufficient to effect the
necessary changes.
