An update that fixes three vulnerabilities is now available.
Description:
This update for the Linux Kernel 3.12.74-60_64_66 fixes several issues.
The following security issues were fixed:
- CVE-2018-3646: Local attackers in virtualized guest systems could use
speculative code patterns on hyperthreaded processors to read data
present in the L1 Datacache used by other hyperthreads on the same CPU
core, potentially leaking sensitive data, even from other virtual
machines or the host system (bsc#1099306).
- CVE-2017-11600: net/xfrm/xfrm_policy.c did not ensure that the dir value
of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local
users to cause a denial of service (out-of-bounds access) or possibly
have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink
message (bsc#1096564)
- CVE-2018-10853: A flaw was found in kvm. In which certain instructions
such as sgdt/sidt call segmented_write_std didn't propagate access
correctly. As such, during userspace induced exception, the guest can
incorrectly assume that the exception happened in the kernel and panic.
(bsc#1097108).
