1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200702-01 / samba
Release Date February 13, 2007
Latest Revision February 13, 2007: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
net-fs/samba < 3.0.24 >= 3.0.24 All supported architectures

Related bugreports: #165549


Multiple flaws exist in the Samba suite of programs, the most serious of which could result in the execution of arbitrary code.

2.  Impact Information


Samba is a suite of SMB and CIFS client/server programs for UNIX.


A format string vulnerability exists in the VFS module when handling AFS file systems and an infinite loop has been discovered when handling file rename operations.


A user with permission to write to a shared AFS file system may be able to compromise the smbd process and execute arbitrary code with the permissions of the daemon. The infinite loop could be abused to consume excessive resources on the smbd host, denying service to legitimate users.

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-3.0.24"
