HIDBench: Benchmarking Large Language Models for Host-Based Intrusion Detection

Recent benchmark efforts have advanced the evaluation of large language models LLMs in cybersecurity, including tasks such as penetration testing and vulnerability identification. However, a critical cybersecurity task, namely intrusion detection from system logs, remains unexplored. In this work...

Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: openssh (UTSA-2026-016492)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016492 advisory. OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted ...

EUVD-2026-18817

A flaw was found in util-linux. Improper hostname canonicalization in the login1 utility, when invoked with the -h option, can modify the supplied remote hostname before setting PAMRHOST. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing...

CVE-2026-3184

A flaw was found in util-linux. Improper hostname canonicalization in the login1 utility, when invoked with the -h option, can modify the supplied remote hostname before setting PAMRHOST. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing...

CVE-2026-3184

Affects util-linux, specifically the login(1) utility when invoked with -h. The root cause is improper hostname canonicalization, which can modify the supplied remote hostname before setting PAM_RHOST. This weakness can bypass host-based PAM access control rules that rely on fully qualified domai...

CVE-2026-3184 Util-linux: util-linux: access control bypass due to improper hostname canonicalization

A flaw was found in util-linux. Improper hostname canonicalization in the login1 utility, when invoked with the -h option, can modify the supplied remote hostname before setting PAMRHOST. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing...

DEBIAN-CVE-2026-35387

OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA algorithms...

Always-Incorrect Control Flow Implementation

Overview Affected versions of this package are vulnerable to Always-Incorrect Control Flow Implementation due to the misinterpretation of the PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms configuration, which causes unintended ECDSA algorithms to be accepted. An attacker can compromise...

EulerOS 2.0 SP11 : libsoup (EulerOS-SA-2026-1584)

According to the versions of the libsoup packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : A flaw in libsoup's HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing...

CVE-2026-30964

web-auth/webauthn-lib is an open source set of PHP libraries and a Symfony bundle to allow developers to integrate that authentication mechanism into their web applications. Prior to 5.2.4, when allowedorigins is configured, CheckAllowedOrigins reduces URL-like values to their host component and...

Caddy 安全漏洞

Caddy is an open-source, cross-platform HTTP/Web server developed by the Caddy company. Versions of Caddy prior to 2.11.1 contained security vulnerabilities. These vulnerabilities stemmed from the HTTP host request matcher becoming case-sensitive when configuring large host lists, which could all...

libsoup: libsoup: Duplicate Host Header Handling Causes Host-Parsing Discrepancy (First- vs Last-Value Wins)

A flaw in libsoup’s HTTP header handling allows multiple Host: headers in a request and returns the last occurrence for server-side processing. Common front proxies often honor the first Host: header, so this mismatch can cause vhost confusion where a proxy routes a request to one backend but the...
