Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux: Linux kernel Details: It was discovered that the CIFS client implementation in the Linux kernel did not properly handle setup negotiation during session recovery, leading to a NULL pointer exception. An attacker could use this to create a malicious CIFS server that caused a denial of service (client system crash). (CVE-2018-1066) Jann Horn discovered that the procfs file system implementation in the Linux kernel did not properly restrict the ability to inspect the kernel stack of an arbitrary task. A local attacker could use this to expose sensitive information. (CVE-2018-17972) Jann Horn discovered that the mremap() system call in the Linux kernel did not properly flush the TLB when completing, potentially leaving access to a physical page after it has been released to the page allocator. A local attacker could use this to cause a denial of service (system crash), expose sensitive information, or possibly execute arbitrary code. (CVE-2018-18281) It was discovered that the socket implementation in the Linux kernel contained a type confusion error that could lead to memory corruption. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-9568) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
