Releases
Packages
- thunderbird - Mozilla Open Source mail and newsgroup client
Details
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 machine-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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.10
Ubuntu 14.04
Ubuntu 12.04
After a standard system update you need to restart Thunderbird to make
all the necessary changes.
