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

the user invoking Thunderbird. (CVE-2015-2734, CVE-2015-2735,

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)");
