critical Nessus Plugin ID 89776

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Karthikeyan Bhargavan and Gaetan Leurent discovered that NSS incorrectly allowed MD5 to be used for TLS 1.2 connections. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2015-7575)

Yves Younan discovered that graphite2 incorrectly handled certain malformed fonts. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitary code with the privileges of the user invoking Thunderbird. (CVE-2016-1523)

Bob Clary, Christian Holler, Nils Ohlmeier, Gary Kwong, Jesse Ruderman, Carsten Book, and Randell Jesup 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-2016-1930)

Aki Helin discovered a buffer overflow when rendering WebGL content in some circumstances. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Thunderbird. (CVE-2016-1935).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
