Packages
- thunderbird - Mozilla Open Source mail and newsgroup client
Details
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)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.04
Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04
After a standard system update you need to restart Thunderbird to make
all the necessary changes.
