Mandriva Linux Security Advisory 2009:277: samba

Multiple vulnerabilities has been found and corrected in samba:

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 versions of samba shipping with Mandriva Linux
CS4/MES5/2008.1/2009.0/2009.1 have been updated to the latest version
that includes the fixes for these issues. Additionally for 2009.1
the version upgrade provides many upstream bug fixes such as improved
Windows(tm) 7 support. The version for CS3 has been patched to address
these security issues...
