| Description: | Summary:
The remote host is missing an update for the 'Linux Kernel (Live Patch 25 for SLE 12 SP2)' package(s) announced via the SUSE-SU-2018:3470-1 advisory.
Vulnerability Insight:
This update for the Linux Kernel 4.4.121-92_95 fixes several issues.
The following security issues were fixed:
CVE-2018-14633: A security flaw was found in the
chap_server_compute_md5() function in the ISCSI target code in a way an
authentication request from an ISCSI initiator is processed. An
unauthenticated remote attacker can cause a stack buffer overflow and
smash up to 17 bytes of the stack. The attack requires the iSCSI target
to be enabled on the victim host. Depending on how the target's code was
built (i.e. depending on a compiler, compile flags and hardware
architecture) an attack may lead to a system crash and thus to a
denial-of-service or possibly to a non-authorized access to data
exported by an iSCSI target. Due to the nature of the flaw, privilege
escalation cannot be fully ruled out, although we believe it is highly
unlikely. (bsc#1107832).
CVE-2018-5390: The Linux kernel could be forced to make very expensive
calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every
incoming packet which can lead to a denial of service (bsc#1102682).
Affected Software/OS:
'Linux Kernel (Live Patch 25 for SLE 12 SP2)' package(s) on SUSE Linux Enterprise Server 12-SP2, SUSE Linux Enterprise Server for SAP 12-SP2.
Solution:
Please install the updated package(s).
