Multiple vulnerabilities were discovered and fixed in Samba, a SMB/CIFS
file, print, and login server:
- CVE-2014-0178
Information leak vulnerability in the VFS code, allowing an
authenticated user to retrieve eight bytes of uninitialized memory
when shadow copy is enabled.
- CVE-2014-0244
Denial of service (infinite CPU loop) in the nmbd Netbios name
service daemon. A malformed packet can cause the nmbd server to
enter an infinite loop, preventing it to process later requests to
the Netbios name service.
- CVE-2014-3493
Denial of service (daemon crash) in the smbd file server daemon. An
authenticated user attempting to read a Unicode path using a
non-Unicode request can force the daemon to overwrite memory at an
invalid address.
For the stable distribution (wheezy), these problems have been fixed in
version 2:3.6.6-6+deb7u4.
For the testing distribution (jessie), these problems have been fixed in
version 2:4.1.9+dfsg-1.
For the unstable distribution (sid), these problems have been fixed in
version 2:4.1.9+dfsg-1.
We recommend that you upgrade your samba packages.
