The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:1348 advisory.

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

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
