Advisories MDVSA-2009:320: samba

[paul]

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.
