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.

SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionA sandbox escape was discovered in Firefox. 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 Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass same origin restrictions, conduct cross-site scripting (XSS) attacks, conduct cross-site request forgery (CSRF) attacks, spoof origin attributes, spoof the addressbar contents, bypass safebrowsing protections, or execute arbitrary code.

It was discovered that Firefox 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.
SolutionUpdate the affected firefox package.
