Description

Updated samba packages fix security vulnerabilities Updated ldb and samba packages fix security vulnerabilities: A malicious client can send packets that cause the LDAP server in the samba daemon process to become unresponsive, preventing the server from servicing any other requests (CVE-2015-3223). Versions of Samba from 3.0.0 to 4.3.2 inclusive are vulnerable to a bug in symlink verification, which under certain circumstances could allow client access to files outside the exported share path (CVE-2015-5252). Versions of Samba from 3.2.0 to 4.3.2 inclusive do not ensure that signing is negotiated when creating an encrypted client connection to a server. Without this, a man-in-the-middle attack could downgrade the connection and connect using the supplied credentials as an unsigned, unencrypted connection (CVE-2015-5296). Versions of Samba from 3.2.0 to 4.3.2 inclusive are vulnerable to a missing access control check in the vfs_shadow_copy2 module, which could allow unauthorized users to access snapshots (CVE-2015-5299). A malicious client can send packets that cause the LDAP server in the samba daemon process to return heap memory beyond the length of the requested value. This memory may contain data that the client should not be allowed to see, allowing compromise of the server (CVE-2015-5330). The talloc, tdb, tevent, and ldb packages have been updated to their lastest versions, and the samba package has been patched to fix these issues.
