SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2016:1019-1)

critical Nessus Plugin ID 90531

Language:

Synopsis

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

Description

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.57 to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2015-8812: A flaw was found in the CXGB3 kernel driver when the network was considered congested. The kernel would incorrectly misinterpret the congestion as an error condition and incorrectly free/clean up the skb. When the device would then send the skb's queued, these structures would be referenced and may panic the system or allow an attacker to escalate privileges in a use-after-free scenario. (bsc#966437)

- CVE-2015-8816: A malicious USB device could cause a kernel crash in the USB hub driver. (bnc#968010).

- CVE-2016-2143: On zSeries a fork of a large process could have caused memory corruption due to incorrect page table handling. (bnc#970504)

- CVE-2016-2184: A malicious USB device could cause a kernel crash in the alsa usb-audio driver. (bsc#971125).

- CVE-2016-2384: A malicious USB device could cause a kernel crash in the alsa usb-audio driver. (bsc#966693)

- CVE-2016-2782: A malicious USB device could cause a kernel crash in the usb visor driver. (bnc#968670).

- CVE-2016-3139: A malicious USB device could cause a kernel crash in the wacom driver. (bnc#970909).

- CVE-2016-3156: Removal of ipv4 interfaces with a large number of IP addresses was taking very long.
(bsc#971360).

- CVE-2015-8709: kernel/ptrace.c in the Linux kernel mishandled uid and gid mappings, which allowed local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor states 'there is no kernel bug here (bnc#960561).

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.
