Debian DSA-2109-1 : samba - buffer overflow

high Nessus Plugin ID 49275

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

A vulnerability has been discovered in samba, a SMB/CIFS file, print, and login server for Unix.

The sid_parse() function does not correctly check its input lengths when reading a binary representation of a Windows SID (Security ID).
This allows a malicious client to send a sid that can overflow the stack variable that is being used to store the SID in the Samba smbd server. (CVE-2010-3069 )

Solution

Upgrade the samba packages. The packages for the mips architecture are not included in this upgrade. They will be released as soon as they become available.

For the stable distribution (lenny), this problem has been fixed in version 3.2.5-4lenny13.
