Ubuntu 16.04 LTS / 17.04 : sssd vulnerability (USN-3526-1)

Medium Nessus Plugin ID 105749


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that SSSD incorrectly handled certain inputs when querying its local cache. An attacker could use this to inject arbitrary code and expose sensitive information.

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.


Update the affected sssd, sssd-common and / or sssd-tools packages.
