USN-41-1: Samba vulnerability

18 December 2004

samba vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 4.10

Software Description

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

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
