Synopsis

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

Description

The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.176 to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-9213: expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bnc#1128166).

CVE-2019-2024: A use-after-free when disconnecting a source was fixed which could lead to crashes. bnc#1129179).

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.
