Synopsis

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

Description

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.140 to receive various security and bugfixes. The following security bugs were fixed :

- CVE-2018-13053: The alarm_timer_nsleep function had an integer overflow via a large relative timeout because ktime_add_safe was not used (bnc#1099924)

- CVE-2018-9385: Prevent overread of the 'driver_override' buffer (bsc#1100491)

- CVE-2018-13405: The inode_init_owner function allowed local users to create files with an unintended group ownership allowing attackers to escalate privileges by making a plain file executable and SGID (bnc#1100416)

- CVE-2018-13406: An integer overflow in the uvesafb_setcmap function could have result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1100418)

The update package also includes non-security fixes. See advisory for details.

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.
