news 28 Posted June 22, 2017 ========================================================================== Kernel Live Patch Security Notice LSN-0024-1 June 21, 2017 linux vulnerability ========================================================================== A security issue affects these releases of Ubuntu: | Series | Base kernel | Arch | flavors | |------------------+--------------+----------+------------------| | Ubuntu 16.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | lowlatency | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | lowlatency | Summary: Several security issues were fixed in the kernel. Software Description: - linux: Linux kernel Details: It was discovered that the stack guard page for processes in the Linux kernel was not sufficiently large enough to prevent overlapping with the heap. An attacker could leverage this with another vulnerability to execute arbitrary code and gain administrative privileges (CVE-2017-1000364) Update instructions: The problem can be corrected by up[censored] your livepatches to the following versions: | Kernel | Version | flavors | |-----------------+----------+--------------------------| | 4.4.0-21.37 | 24.2 | generic, lowlatency | | 4.4.0-22.39 | 24.2 | generic, lowlatency | | 4.4.0-22.40 | 24.2 | generic, lowlatency | | 4.4.0-24.43 | 24.2 | generic, lowlatency | | 4.4.0-28.47 | 24.2 | generic, lowlatency | | 4.4.0-31.50 | 24.2 | generic, lowlatency | | 4.4.0-34.53 | 24.2 | generic, lowlatency | | 4.4.0-36.55 | 24.2 | generic, lowlatency | | 4.4.0-38.57 | 24.2 | generic, lowlatency | | 4.4.0-42.62 | 24.2 | generic, lowlatency | | 4.4.0-43.63 | 24.2 | generic, lowlatency | | 4.4.0-45.66 | 24.2 | generic, lowlatency | | 4.4.0-47.68 | 24.2 | generic, lowlatency | | 4.4.0-51.72 | 24.2 | generic, lowlatency | | 4.4.0-53.74 | 24.2 | generic, lowlatency | | 4.4.0-57.78 | 24.2 | generic, lowlatency | | 4.4.0-59.80 | 24.2 | generic, lowlatency | | 4.4.0-62.83 | 24.2 | generic, lowlatency | | 4.4.0-63.84 | 24.2 | generic, lowlatency | | 4.4.0-64.85 | 24.2 | generic, lowlatency | | 4.4.0-66.87 | 24.2 | generic, lowlatency | | 4.4.0-67.88 | 24.2 | generic, lowlatency | | 4.4.0-70.91 | 24.2 | generic, lowlatency | | 4.4.0-71.92 | 24.2 | generic, lowlatency | | 4.4.0-72.93 | 24.2 | generic, lowlatency | | 4.4.0-75.96 | 24.2 | generic, lowlatency | | 4.4.0-77.98 | 24.2 | generic, lowlatency | | 4.4.0-78.99 | 24.2 | generic, lowlatency | | 4.4.0-79.100 | 24.2 | generic, lowlatency | | lts-4.4.0-21.37_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-22.39_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-22.40_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-24.43_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-28.47_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-31.50_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-34.53_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-36.55_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-38.57_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-42.62_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-45.66_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-47.68_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-51.72_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-53.74_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-57.78_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-59.80_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-62.83_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-63.84_14.04.2-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-64.85_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-66.87_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-70.91_14.04.1-lts-xenial | 24.2 | generic, lowlatency | | lts-4.4.0-71.92_14.04.1-lts-xenial | 24.2 | generic, lowlatency | Additionally, you should install an updated kernel with these fixes and reboot at your convienience.
