script_tag(name:"insight", value:"Several vulnerabilities have been discovered in Samba, a SMB/CIFS file, print, and login server for Unix. The Common Vulnerabilities and Exposures project identifies the following issues:
CVE-2015-7560
Jeremy Allison of Google, Inc. and the Samba Team discovered that Samba incorrectly handles getting and setting ACLs on a symlink path. An authenticated malicious client can use SMB1 UNIX extensions to create a symlink to a file or directory, and then use non-UNIX SMB1 calls to overwrite the contents of the ACL on the file or directory linked to.
CVE-2016-0771
Garming Sam and Douglas Bagnall of Catalyst IT discovered that Samba is vulnerable to an out-of-bounds read issue during DNS TXT record handling, if Samba is deployed as an AD DC and chosen to run the internal DNS server. A remote attacker can exploit this flaw to cause a denial of service (Samba crash), or potentially, to allow leakage of memory from the server in the form of a DNS TXT reply.
Additionally this update includes a fix for a regression introduced due to the upstream fix for CVE-2015-5252 in DSA-3433-1 in setups where the share path is '/'.
For the oldstable distribution (wheezy), these problems have been fixed in version 2:3.6.6-6+deb7u7. The oldstable distribution (wheezy) is not affected by CVE-2016-0771.
For the stable distribution (jessie), these problems have been fixed in version 2:4.1.17+dfsg-2+deb8u2.
For the unstable distribution (sid), these problems have been fixed in version 2:4.3.6+dfsg-1.
We recommend that you upgrade your samba packages.");
