Ubuntu 14.04 LTS : Samba vulnerabilities (USN-2922-1)

medium Nessus Plugin ID 89777

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2922-1 advisory.

Jeremy Allison discovered that Samba incorrectly handled ACLs on symlink paths. A remote attacker could use this issue to overwrite the ownership of ACLs using symlinks. (CVE-2015-7560)

Garming Sam and Douglas Bagnall discovered that the Samba internal DNS server incorrectly handled certain DNS TXT records. A remote attacker could use this issue to cause Samba to crash, resulting in a denial of service, or possibly obtain uninitialized memory contents. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 15.10. (CVE-2016-0771)

It was discovered that the Samba Web Administration Tool (SWAT) was vulnerable to clickjacking and cross- site request forgery attacks. This issue only affected Ubuntu 12.04 LTS. (CVE-2013-0213, CVE-2013-0214)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
