USN-41-1: Samba vulnerability

Publication date

18 December 2004

Overview

Samba vulnerability

Releases

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.
