thunderbird vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 19.04
o Ubuntu 18.10
o Ubuntu 18.04 LTS
o Ubuntu 16.04 LTS
Summary
Several security issues were fixed in Thunderbird.
Software Description
o thunderbird - Mozilla Open Source mail and newsgroup client
Details
A sandbox escape was discovered in Thunderbird. If a user were tricked in to
installing a malicious language pack, an attacker could exploit this to gain
additional privileges. (CVE-2019-9811)
Multiple security issues were discovered 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, bypass same
origin restrictions, conduct cross-site scripting (XSS) attacks, spoof origin
attributes, or execute arbitrary code. (CVE-2019-11709, CVE-2019-11711,
CVE-2019-11712, CVE-2019-11713, CVE-2019-11715, CVE-2019-11717)
It was discovered that NSS incorrectly handled importing certain curve25519
private keys. An attacker could exploit this issue to cause Thunderbird to
crash, resulting in a denial of service, or possibly obtain sensitive
information. (CVE-2019-11719)
It was discovered that NSS incorrectly handled certain p256-ECDH public keys.
An attacker could possibly exploit this issue to cause Thunderbird to crash,
resulting in a denial of service. (CVE-2019-11729)
It was discovered that Thunderbird treats all files in a directory as same
origin. If a user were tricked in to downloading a specially crafted HTML file,
an attacker could potentially exploit this to obtain sensitive information from
local files. (CVE-2019-11730)
