Two security vulnerabilities have been discovered in the OpenSSH secure networking utility suite that, if successfully exploited, could result in an active machine-in-the-middle (MitM) and a denial-of-service (DoS) attack, respectively, under certain conditions. The vulnerabilities, detailed by the Qualys Threat Research Unit (TRU), are listed below - CVE-2025-26465 (CVSS score: 6.8)  - The OpenSSH client contains a logic error between versions 6.8p1 to 9.9p1 (inclusive) that makes it vulnerable to an active MitM attack if the VerifyHostKeyDNS option is enabled, allowing a malicious interloper to impersonate a legitimate server when a client attempts to connect to it (Introduced in December 2014) CVE-2025-26466 (CVSS score: 5.9) - The OpenSSH client and server are vulnerable to a pre-authentication DoS attack between versions 9.5p1 to 9.9p1 (inclusive) that causes memory and CPU consumption (Introduced in August 2023) "If an attacker can perform a man-in-the-middle a...

Fedora 14, known as "Laughlin," officially launched on Tuesday, offering numerous new features aimed at enhancing the user experience for this open-source desktop operating system.

This library "practically halves processing time on most systems," claim the developers, even benefiting those on older hardware. Another notable feature is SPICE (Simple Protocol for Independent Computing Environment), a desktop virtualization framework enha...
