New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

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-like context, an attacker could potentially exploit these to bypass same-origin restrictions, cause a denial of service via application crash, or execute arbitrary code. (CVE-2017-7826, CVE-2017-7828, CVE-2017-7830).
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.
