New! Plugin Severity Now Using CVSS v3

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 3.12.74-60_64_107 fixes one issue.

The following security issue was fixed :

CVE-2018-18386: The drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bsc#1112039).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
