Scroll support has been removed from the Linux kernel console

Posted on

As a result of the vulnerability check, support for scrolling buffers was removed from the vgacon and fbcon drivers. With the new kernel versions, scrolling the console using Ctrl-PgUp/PgDn will no longer be possible. Linus Torvalds has promised to reintegrate the code into the kernel if a new maintainer can be found to handle the buffer overflow checks. It seems all developers have shifted to graphical interfaces, and the bare console has been largely abandoned. […]

IPSec tunnel between Strongswan behind NAT and VMWare NSX Edge

For a number of reasons, it was necessary to set up a VPN connection between the network in VMWare Cloud Director and a separate Ubuntu machine in the cloud. This note does not claim to be a complete description; it is just a small how-to. The only article found on this topic is from 2015: 'Site to Site IPSEC VPN between NSX Edge and Linux strongSwan.' Unfortunately, it cannot be used directly […]

The implementation of the domain controller in Samba was found to be vulnerable to the ZeroLogin exploit

Posted on

The developers of the Samba project have warned users that the recently discovered ZeroLogin vulnerability (CVE-2020-1472) in Windows also manifests in the Samba domain controller implementation. The vulnerability is caused by shortcomings in the MS-NRPC protocol and the AES-CFB8 cryptographic algorithm, and if exploited successfully, it allows an attacker to gain administrator access in the domain controller. The essence of the vulnerability is that the MS-NRPC (Netlogon Remote Protocol) protocol allows […]
