SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionUSN-1758-1 fixed vulnerabilities in Firefox. This update provides the corresponding update for Thunderbird.
It was discovered that Firefox contained a memory safety issue. If a user were tricked into opening a specially crafted page with the HTML editor, a remote attacker could exploit this to execute arbitrary code with the privileges of the user invoking the program.
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 thunderbird package.
