USN-41-1: Samba vulnerability

Releases

• Ubuntu 4.10

Details

Greg MacManus discovered an integer overflow in Samba's smbd daemon.
Requesting a very large number of access control descriptors from the
server caused an integer overflow, which resulted in a memory
allocation being too short, thus causing a buffer overflow. By sending
carefully crafted data, an attacker could exploit this to execute
arbitrary code on the server with full root permissions.

Update instructions

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

Ubuntu 4.10

• samba -

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