Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : samba vulnerability (USN-3348-1)
High Nessus Plugin ID 101262
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that Samba incorrectly handled dangling symlinks. A remote attacker could possibly use this issue to cause Samba to hang, resulting in a denial of service. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-9461)
In addition, this update fixes a regression introduced by USN-3267-1 that caused Samba to incorrectly handle non-wide symlinks to directories.
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 samba package.
