Q3 2024 saw multiple vulnerabilities discovered in Windows and Linux subsystems that are not standard for cyberattacks. This is because operating system developers have been releasing new security mitigations for whole sets of vulnerabilities in commonly used subsystems. For example, a log integrity check is set to appear in the Common Log Filing System (CLFS) in Windows, so the number of exploits for it will drop. As for Linux, this operating system has the Linux Kernel Runtime Guard (LKRG), im...

New regreSSHion OpenSSH RCE bug gives root on Linux servers By Bill Toulas July 1, 2024 09:37 AM 1 A new OpenSSH unauthenticated remote code execution (RCE) vulnerability dubbed "regreSSHion" gives root privileges on glibc-based Linux systems. OpenSSH is a suite of networking utilities based on the Secure Shell (SSH) protocol. It is extensively used for secure remote login, remote server management and administration, and file transfers via SCP and SFTP. The flaw, discovered by researc...

The founder of Openwall has discovered a new signal handler race condition in the core sshd daemon used in RHEL 9.x and its various offshoots. The new flaw, catchily dubbed CVE-2024-6409, was found by Openwall's Alexander Peslyak, known in the security world as Solar Designer. It affects the sshd daemon versions 8.7p1 and 8.8p1, which were used in Fedora 36 and 37 as well as Red Hat Enterprise Linux 9 – and of course the various RHELatives as well.

Glibc-based Linux systems are vulnerable to a new bug (CVE-2024-6387) in OpenSSH's server (sshd) and should upgrade to the latest version. Infosec researchers at Qualys published their findings today, revealing that sshd is vulnerable to a race condition that could allow an unauthenticated attacker to achieve remote code execution (RCE) on potentially hundreds of thousands of targets. Of the 14 million potentially vulnerable sshd instances that show up on Censys and Shodan scans, Qualys believes...
