ABB is aware of public reports of the vulnerabilities in the product versions listed as affected in this advisory. An attacker who successfully exploited modem module vulnerabilities could run arbitrary code in the wireless modem module of the product. This could lead to denial of service or tampering with unencrypted traffic. An attacker who successfully exploited the OpenSSH vulnerability could run arbitrary code in the product with privileged user permissions. This could cause the product to stop, make the product inaccessible, or the attacker could take control of the product. As part of ABB product lifecycle policy, once a product transitions to Limited state, we discontinue maintenance, security patches, and technical support to focus on current and future technologies. While the product will continue to function, we strongly recommend implementing mitigations defined in this document to mitigate security risks.
Affected: AlmaLinux:9: openssh, AlmaLinux:9: openssh-askpass, AlmaLinux:9: openssh-clients, AlmaLinux:9: openssh-keycat, AlmaLinux:9: openssh-server, AlmaLinux:9: pam_ssh_agent_auth
OpenSSH is an SSH protocol implementation supported by a number of Linux, UNIX, and similar operating systems. It includes the core files necessary for both the OpenSSH client and server.
Security Fix(es):
* openssh: Possible remote code execution due to a race condition in signal handling (CVE-2024-6387)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Affected: Alpaquita:23: openssh, Alpaquita:stream: openssh, BellSoft Hardened Containers:23: openssh, BellSoft Hardened Containers:stream: openssh
On July 1, 2024, the Qualys Threat Research Unit (TRU) disclosed an unauthenticated, remote code execution vulnerability that affects the OpenSSH server (sshd) in glibc-based Linux systems. CVE-2024-6387: A signal handler race condition was found in sshd, where a client does not authenticate within LoginGraceTime seconds (120 by default, 600 in old OpenSSH versions), then the sshd SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are not async-signal-safe, for example, syslog(). For a description of this vulnerability, see the Qualys Security Advisory ["https://www.qualys.com/2024/07/01/cve-2024-6387/regresshion.txt"].
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

Affected: openEuler:24.03-LTS: openssh
OpenSSH is the premier connectivity tool for remote login with the SSH protocol. \ It encrypts all traffic to eliminate eavesdropping, connection hijacking, and \ other attacks. In addition, OpenSSH provides a large suite of secure tunneling \ capabilities, several authentication methods, and sophisticated configuration options.

openssh: regreSSHion - race condition in SSH allows RCE/DoS
Multiple vulnerabilities have been identified in the additional GNU/Linux subsystem of the firmware version V3.1.5 for the SIMATIC S7-1500 CPU 1518(F)-4 PN/DP MFP (incl. SIPLUS variant).
Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.
Note: This SSA advises vulnerabilities for firmware version V3.1.5 only; for version V3.1.6 refer to SSA-019113.

TruControl laser control software prior to version 1.60.0 uses an OpenSSH server version affected by CVE-2024-6387. The affected OpenSSH Server version could potentially lead to a remote code execution.
Several Red Lion Europe products are vulnerable to a possible race condition vulnerability in OpenSSH named "regreSSHion".
Products from the Edge Gateway Family are affected by recently published so called RegreSSHion vulnerability.
Several Helmholz products are vulnerable to a possible race condition vulnerability in OpenSSH named "regreSSHion".
mGuards use an OpenSSH server for SSH access. This server is vulnerable to a remote code injection.
The affected devices run a SSH server that is affected by the regreSSHion vulnerability despite the fact that no user can actually log in through SSH. Attackers may exploit this vulnerability to gain root access to the device.
