Gentoo Linux Security Advisory

Title: Samba: Multiple vulnerabilities (GLSA 200411-21)
Severity: normal
Exploitable: remote
Date: November 11, 2004
Updated: November 15, 2004
Bug(s): #70429
ID: 200411-21


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.

Affected Packages

Package: net-fs/samba
Vulnerable: < 3.0.8
Unaffected: >= 3.0.8
Unaffected: < 3.0
Architectures: All supported architectures


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"
