========================================================================== Kernel Live Patch Security Notice 0062-1 February 03, 2020 linux vulnerability ========================================================================== A security issue affects these releases of Ubuntu: | Series | Base kernel | Arch | flavors | |------------------+--------------+----------+------------------| | Ubuntu 18.04 LTS | 4.15.0 | amd64 | aws | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | generic | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | lowlatency | | Ubuntu 18.04 LTS | 4.15.0 | amd64 | oem | | Ubuntu 18.04 LTS | 5.0.0 | amd64 | azure | | Ubuntu 18.04 LTS | 5.0.0 | amd64 | gcp | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 14.04 LTS | 4.4.0 | amd64 | lowlatency | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | aws | | Ubuntu 16.04 LTS | 4.4.0 | amd64 | generic | | Ubuntu 16.04 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 binder IPC implementation in the Linux kernel did not properly perform bounds checking in some situations, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-2214) It was discovered that the Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors. A local attacker could use this to expose sensitive information. (CVE-2019-14615) It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895) It was discovered that a heap-based buffer overflow existed in the Marvell Libertas WLAN Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14896) It was discovered that a heap-based buffer overflow existed in the Marvell Libertas WLAN Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14897) It was discovered that a heap-based buffer overflow existed in the Marvell WiFi-Ex Driver for the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14901) It was discovered that the btrfs file system in the Linux kernel did not properly validate metadata, leading to a NULL pointer dereference. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2019-18885) Update instructions: The problem can be corrected by updating your livepatches to the following versions: | Kernel | Version | flavors | |--------------------------+----------+--------------------------| | 4.4.0-168.197 | 62.2 | generic, lowlatency | | 4.4.0-168.197~14.04.1 | 62.2 | lowlatency, generic | | 4.4.0-169.198 | 62.2 | generic, lowlatency | | 4.4.0-169.198~14.04.1 | 62.2 | lowlatency, generic | | 4.4.0-170.199 | 62.2 | lowlatency, generic | | 4.4.0-170.199~14.04.1 | 62.2 | lowlatency, generic | | 4.4.0-171.200 | 62.2 | lowlatency, generic | | 4.4.0-1098.109 | 62.2 | aws | | 4.4.0-1099.110 | 62.2 | aws | | 4.4.0-1100.111 | 62.2 | aws | | 4.15.0-69.78 | 62.2 | generic, lowlatency | | 4.15.0-70.79 | 62.2 | lowlatency, generic | | 4.15.0-72.81 | 62.2 | generic, lowlatency | | 4.15.0-74.84 | 62.2 | generic, lowlatency | | 4.15.0-1054.56 | 62.2 | aws | | 4.15.0-1056.58 | 62.2 | aws | | 4.15.0-1057.59 | 62.2 | aws | | 4.15.0-1063.72 | 62.2 | oem | | 4.15.0-1064.73 | 62.2 | oem | | 4.15.0-1065.75 | 62.2 | oem | | 4.15.0-1066.76 | 62.2 | oem | | 5.0.0-1025.26~18.04.1 | 62.2 | gcp | | 5.0.0-1025.27~18.04.1 | 62.2 | azure | | 5.0.0-1026.27~18.04.1 | 62.2 | gcp | Support Information: Kernels older than the levels listed below do not receive livepatch updates.
