Debian Security Advisory

DSA-262-1 samba -- remote exploit

Date Reported:

15 Mar 2003

Affected Packages:

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 7107, BugTraq ID 7106.
In Mitre's CVE dictionary: CVE-2003-0085, CVE-2003-0086.

More information:

Sebastian Krahmer of the SuSE security audit team found two problems in samba, a popular SMB/CIFS implementation. The problems are:

a buffer overflow in the SMB/CIFS packet fragment re-assembly code used by smbd. Since smbd runs as root an attacker can use this to gain root access to a machine running smbd.
the code to write reg files was vulnerable for a chown race which made it possible for a local user to overwrite system files

Both problems have been fixed in upstream version 2.2.8, and version 2.2.3a-12.1 of package for Debian GNU/Linux 3.0/woody.

Fixed in:

Debian GNU/Linux 3.0 (woody)
