low Nessus Plugin ID 221190
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task's default request-key keyring via the request_key() system call, allowing a local user to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.
(CVE-2017-17807)
Note that Nessus relies on the presence of the package as reported by the vendor.
