Background ========== Samba is a suite of SMB and CIFS client/server programs for UNIX. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/samba < 3.0.24 >= 3.0.24 Description =========== 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. Impact ====== 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. Workaround ========== There is no known workaround at this time. Resolution ========== All Samba users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.24" References ========== [ 1 ] CVE-2007-0452 http://samba.org/samba/security/CVE-2007-0452.html [ 2 ] CVE-2007-0454 http://samba.org/samba/security/CVE-2007-0454.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200702-01.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
