Mandriva Linux Security Advisory : samba (MDVSA-2009:320)
medium Nessus Plugin ID 43023
Synopsis
The remote Mandriva Linux host is missing one or more security updates.Description
Multiple vulnerabilities has been found and corrected in samba :The acl_group_override function in smbd/posix_acls.c in smbd in Samba 3.0.x before 3.0.35, 3.1.x and 3.2.x before 3.2.13, and 3.3.x before 3.3.6, when dos filemode is enabled, allows remote attackers to modify access control lists for files via vectors related to read access to uninitialized memory (CVE-2009-1888).
The SMB (aka Samba) subsystem in Apple Mac OS X 10.5.8, when Windows File Sharing is enabled, does not properly handle errors in resolving pathnames, which allows remote authenticated users to bypass intended sharing restrictions, and read, create, or modify files, in certain circumstances involving user accounts that lack home directories (CVE-2009-2813).
smbd in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8, and 3.4 before 3.4.2 allows remote authenticated users to cause a denial of service (infinite loop) via an unanticipated oplock break notification reply packet (CVE-2009-2906).
mount.cifs in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8 and 3.4 before 3.4.2, when mount.cifs is installed suid root, does not properly enforce permissions, which allows local users to read part of the credentials file and obtain the password by specifying the path to the credentials file and using the --verbose or
-v option (CVE-2009-2948).
The version of samba shipping with Mandriva Linux 2008.0 has been updated to the latest version (3.0.37) that includes the fixes for these issues.
