Local man-in-the-middle and SSH security downgrade in libssh on Windows stems from the library automatically loading configuration files from C:\etc, a directory that any unprivileged local user can create and populate. By planting a malicious config, an attacker can manipulate trusted host data and weaken SSH cryptographic negotiation, compromising the confidentiality, integrity, and availability of SSH sessions established by applications linking libssh. There is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and it is not in CISA KEV.
Improper hostname canonicalization in util-linux login(1) utility with the -h option allows remote attackers to bypass host-based PAM access control rules by supplying specially crafted hostnames that are modified before being passed to PAM_RHOST, potentially leading to unauthorized access. The vulnerability affects Red Hat Enterprise Linux 7 through 10 and related products; exploitation requires high attack complexity but no authentication or user interaction. No public exploit code has been identified, and this is not currently confirmed as actively exploited.
Denial of service in rust-rpm-sequoia allows local attackers to crash RPM signature verification by submitting specially crafted RPM files that trigger unhandled errors in OpenPGP parsing, preventing legitimate package management operations. CVSS 4.0 (low severity), local attack vector, non-authenticating. No public exploit code or active exploitation confirmed.
