Samba is vulnerable to a buffer overflow that could lead to execution of arbitrary code (CAN-2004-0882). Another flaw in Samba may allow a remote attacker to cause a Denial of Service by excessive consumption of CPU cycles (CAN-2004-0930).

Samba is a freely available SMB/CIFS implementation which allows seamless interoperability of file and print services to other SMB/CIFS clients.
Samba fails to do proper bounds checking when handling TRANSACT2_QFILEPATHINFO replies. Additionally an input validation flaw exists in ms_fnmatch.c when matching filenames that contain wildcards.
An attacker may be able to execute arbitrary code with the permissions of the user running Samba. A remote attacker may also be able to cause an abnormal consumption of CPU resources, resulting in slower performance of the server or even a Denial of Service.
There is no known workaround at this time.
All Samba users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.8"
