========================================================================== Ubuntu Security Notice USN-4579-1 October 14, 2020
linux, linux-aws, linux-kvm, linux-lts-xenial, linux-raspi2, linux-snapdragon vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS - Ubuntu 14.04 ESM
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel - linux-aws: Linux kernel for Amazon Web Services (AWS) systems - linux-kvm: Linux kernel for cloud environments - linux-raspi2: Linux kernel for Raspberry Pi (V8) systems - linux-snapdragon: Linux kernel for Qualcomm Snapdragon processors - linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty
Details:
Hador Manor discovered that the DCCP protocol implementation in the Linux kernel improperly handled socket reuse, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-16119)
Wen Xu discovered that the XFS file system in the Linux kernel did not properly validate inode metadata in some situations. An attacker could use this to construct a malicious XFS image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10322)
Jay Shin discovered that the ext4 file system implementation in the Linux kernel did not properly handle directory access with broken indexing, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-14314)
It was discovered that a race condition existed in the hugetlb sysctl implementation in the Linux kernel. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2020-25285)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: linux-image-4.4.0-1082-kvm 4.4.0-1082.91 linux-image-4.4.0-1117-aws 4.4.0-1117.131 linux-image-4.4.0-1141-raspi2 4.4.0-1141.151 linux-image-4.4.0-1145-snapdragon 4.4.0-1145.155 linux-image-4.4.0-193-generic 4.4.0-193.224 linux-image-4.4.0-193-generic-lpae 4.4.0-193.224 linux-image-4.4.0-193-lowlatency 4.4.0-193.224 linux-image-4.4.0-193-powerpc-e500mc 4.4.0-193.224 linux-image-4.4.0-193-powerpc-smp 4.4.0-193.224 linux-image-4.4.0-193-powerpc64-emb 4.4.0-193.224 linux-image-4.4.0-193-powerpc64-smp 4.4.0-193.224 linux-image-aws 4.4.0.1117.122 linux-image-generic 4.4.0.193.199 linux-image-generic-lpae 4.4.0.193.199 linux-image-kvm 4.4.0.1082.80 linux-image-lowlatency 4.4.0.193.199 linux-image-powerpc-e500mc 4.4.0.193.199 linux-image-powerpc-smp 4.4.0.193.199 linux-image-powerpc64-emb 4.4.0.193.199 linux-image-powerpc64-smp 4.4.0.193.199 linux-image-raspi2 4.4.0.1141.141 linux-image-snapdragon 4.4.0.1145.137 linux-image-virtual 4.4.0.193.199
Ubuntu 14.04 ESM: linux-image-4.4.0-1081-aws 4.4.0-1081.85 linux-image-4.4.0-193-generic 4.4.0-193.224~14.04.1 linux-image-4.4.0-193-generic-lpae 4.4.0-193.224~14.04.1 linux-image-4.4.0-193-lowlatency 4.4.0-193.224~14.04.1 linux-image-aws 4.4.0.1081.78 linux-image-generic-lpae-lts-xenial 4.4.0.193.169 linux-image-generic-lts-xenial 4.4.0.193.169 linux-image-lowlatency-lts-xenial 4.4.0.193.169 linux-image-virtual-lts-xenial 4.4.0.193.169
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.
