Title:RHSA-2018:1355: kernel-rt security and bug fix update (Important)
Description:The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • Kernel: KVM: error in exception handling leads to wrong debug stack value (CVE-2018-1087)

  • Kernel: error in exception handling leads to DoS (CVE-2018-8897)

  • Kernel: ipsec: xfrm: use-after-free leading to potential privilege escalation (CVE-2017-16939)

  • kernel: Out-of-bounds write via userland offsets in ebt_entry struct in netfilter/ebtables.c (CVE-2018-1068)

  • kernel: ptrace() incorrect error handling leads to corruption and DoS (CVE-2018-1000199)

    For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

    Red Hat would like to thank Andy Lutomirski for reporting CVE-2018-1087 and CVE-2018-1000199 and Nick Peterson (Everdox Tech LLC) and Andy Lutomirski for reporting CVE-2018-8897.

    Bug Fix(es):

  • The kernel-rt packages have been upgraded to the 3.10.0-862.2.3 source tree, which provides a number of bug fixes over the previous version. (BZ#1549768)
