Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : Thunderbird vulnerabilities (USN-3793-1)

critical Nessus Plugin ID 118144
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

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, or execute arbitrary code. (CVE-2018-12376, CVE-2018-12377, CVE-2018-12378)

It was discovered that if a user saved passwords before Thunderbird 58 and then later set a master password, an unencrypted copy of these passwords would still be accessible. A local user could exploit this to obtain sensitive information. (CVE-2018-12383)

A crash was discovered in TransportSecurityInfo used for SSL, which could be triggered by data stored in the local cache directory. An attacker could potentially exploit this in combination with another vulnerability that allowed them to write data to the cache, to execute arbitrary code. (CVE-2018-12385).

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.

Solution

Update the affected thunderbird package.
