The maintainers of the FreeBSD Project have released security updates to address a high-severity flaw in OpenSSH that attackers could potentially exploit to execute arbitrary code remotely with elevated privileges. The vulnerability, tracked as CVE-2024-7589, carries a CVSS score of 7.4 out of a maximum of 10.0, indicating high severity. "A signal handler in sshd(8) may call a logging function

Quay.io is Red Hat’s hosted container registry service that serves enterprise users, open source community projects, and Red Hat customers worldwide. One of the most used features of Quay.io, besides storing and serving container images, is the comprehensive security vulnerability reporting for any uploaded image. Because Red Hat is committed to making open source software more accessible, this functionality is also available on the free tier, provided by the Clair static vulnerability analyzer project.Clair allows users to analyze millions of container images and billions of layers, and pr

Select versions of the OpenSSH secure networking suite are susceptible to a new vulnerability that can trigger remote code execution (RCE). The vulnerability, tracked as CVE-2024-6409 (CVSS score: 7.0), is distinct from CVE-2024-6387 (aka RegreSSHion) and relates to a case of code execution in the privsep child process due to a race condition in signal handling. It only impacts versions 8.7p1

Red Hat Security Advisory 2024-4312-03 - An update for openssh is now available for Red Hat Enterprise Linux 9. Issues addressed include a code execution vulnerability.

Ubuntu Security Notice 6859-1 - It was discovered that OpenSSH incorrectly handled signal management. A remote attacker could use this issue to bypass authentication and remotely access systems without proper credentials.

Debian Linux Security Advisory 5724-1 - The Qualys Threat Research Unit (TRU) discovered that OpenSSH, an implementation of the SSH protocol suite, is prone to a signal handler race condition. If a client does not authenticate within LoginGraceTime seconds (120 by default), then sshd's SIGALRM handler is called asynchronously and calls various functions that are not async-signal-safe. A remote unauthenticated attacker can take advantage of this flaw to execute arbitrary code with root privileges. This flaw affects sshd in its default configuration.

Qualys has discovered a a signal handler race condition vulnerability in OpenSSH's server, sshd. If a client does not authenticate within LoginGraceTime seconds (120 by default, 600 in old OpenSSH versions), then sshd's SIGALRM handler is called asynchronously, but this signal handler calls various functions that are not async-signal-safe - for example, syslog(). This race condition affects sshd in its default configuration.

OpenSSH maintainers have released security updates to contain a critical security flaw that could result in unauthenticated remote code execution with root privileges in glibc-based Linux systems. The vulnerability has been assigned the CVE identifier CVE-2024-6387. It resides in the OpenSSH server component, also known as sshd, which is designed to listen for connections from any of the client
