Samba: Integer overflow

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-fs/samba	<= 3.0.9	>= 3.0.9-r1	All supported architectures

Related bugreports: #73943

Samba contains a bug that could lead to remote execution of arbitrary code.

2. Impact Information

Samba is a freely available SMB/CIFS implementation which allows seamless interoperability of file and print services to other SMB/CIFS clients.

Samba contains a bug when unmarshalling specific MS-RPC requests from clients.

A remote attacker may be able to execute arbitrary code with the permissions of the user running Samba, which could be the root user.

3. Resolution Information

There is no known workaround at this time.

All samba users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.9-r1"
