(CVE-2019-3819) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: linux-image-4.15.0-1022-oracle 4.15.0-1022.25 linux-image-4.15.0-1041-gke 4.15.0-1041.43 linux-image-4.15.0-1043-kvm 4.15.0-1043.43 linux-image-4.15.0-1044-raspi2 4.15.0-1044.47 linux-image-4.15.0-60-generic 4.15.0-60.67 linux-image-4.15.0-60-generic-lpae 4.15.0-60.67 linux-image-4.15.0-60-lowlatency 4.15.0-60.67 linux-image-generic 4.15.0.60.62 linux-image-generic-lpae 4.15.0.60.62 linux-image-gke 4.15.0.1041.44 linux-image-gke-4.15 4.15.0.1041.44 linux-image-kvm 4.15.0.1043.43 linux-image-lowlatency 4.15.0.60.62 linux-image-oracle 4.15.0.1022.25 linux-image-powerpc-e500mc 4.15.0.60.62 linux-image-powerpc-smp 4.15.0.60.62 linux-image-powerpc64-emb 4.15.0.60.62 linux-image-powerpc64-smp 4.15.0.60.62 linux-image-raspi2 4.15.0.1044.42 linux-image-virtual 4.15.0.60.62 Ubuntu 16.04 LTS: linux-image-4.15.0-1022-oracle 4.15.0-1022.25~16.04.1 linux-image-4.15.0-1041-gcp 4.15.0-1041.43 linux-image-4.15.0-1056-azure 4.15.0-1056.61 linux-image-4.15.0-60-generic 4.15.0-60.67~16.04.1 linux-image-4.15.0-60-generic-lpae 4.15.0-60.67~16.04.1 linux-image-4.15.0-60-lowlatency 4.15.0-60.67~16.04.1 linux-image-azure 4.15.0.1056.59 linux-image-gcp 4.15.0.1041.55 linux-image-generic-hwe-16.04 4.15.0.60.81 linux-image-generic-lpae-hwe-16.04 4.15.0.60.81 linux-image-gke 4.15.0.1041.55 linux-image-lowlatency-hwe-16.04 4.15.0.60.81 linux-image-oem 4.15.0.60.81 linux-image-oracle 4.15.0.1022.16 linux-image-virtual-hwe-16.04 4.15.0.60.81 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.

security advisorycommand executionlynxRHEL: apache-2.4.46 High Advisory: Vulnerability In Authentication System
When lynx calls external programs for protocols (e.g. telnet), the location is passed unchecked. This can be used to activate commandline parameters. For example, this reference [A HREF="telnet://-n.rhosts"]click me[/A] would activate the tracefile options on the telnet client, with the result, that a .rhosts in the current directory would created or overwritten. . ______________________________________________________________________________ SuSE Security Announcement Package: lynx-2.8.2 and older Date: Thu Sep 16 21:29:15 CEST 1999 Affected: all Linux distributions using lynx-2.8.2 and older ______________________________________________________________________________ A security hole was discovered in the package mentioned above.
