High Nessus Plugin ID 126816

Synopsis

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

Description

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).

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.
