Ubuntu 14.04 LTS : Thunderbird vulnerabilities (USN-2673-1)

medium Nessus Plugin ID 84900

Language:

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-2673-1 advisory.

 Karthikeyan Bhargavan discovered that NSS incorrectly handled state transitions for the TLS state machine.
 If a remote attacker were able to perform a machine-in-the-middle attack, this flaw could be exploited to skip the ServerKeyExchange message and remove the forward-secrecy property. (CVE-2015-2721)

 Bob Clary, Christian Holler, Bobby Holley, and Andrew McCreight discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2015-2724)

 Ronald Crane discovered multiple security vulnerabilities. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740)

 Matthew Green discovered a DHE key processing issue in NSS where a MITM could force a server to downgrade TLS connections to 512-bit export-grade cryptography. An attacker could potentially exploit this to impersonate the server. (CVE-2015-4000)

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.
