Mandriva Linux Security Advisory 2009-196 – Multiple format string vulnerabilities in client/client.c in smbclient in Samba 3.2.0 through 3.2.12 might allow context-dependent attackers to execute arbitrary code via format string specifiers in a filename. 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. This update provides samba 3.2.13 to address these issues.
