SUSE SLED15 / SLES15 Security Update : kernel (SUSE-SU-2019:2710-1)

high Nessus Plugin ID 130089

Language:

Synopsis

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

Description

The SUSE Linux Enterprise 15 SP1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).

CVE-2019-14821: An out-of-bounds access issue was found in the way Linux kernel's KVM hypervisor implements the coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).

CVE-2019-15291: There was a NULL pointer dereference caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).

CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation.
This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).

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.
