High Nessus Plugin ID 117496

Synopsis

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

Description

USN-3761-1 fixed vulnerabilities in Firefox. The update caused several regressions affecting spellchecker dictionaries and search engines.
This update fixes the problems.

We apologize for the inconvenience.

Original advisory details :

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, or execute arbitrary code. (CVE-2018-12375, CVE-2018-12376, CVE-2018-12377, CVE-2018-12378)

It was discovered that if a user saved passwords before Firefox 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).

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 firefox package.
