Keycloak versions 26 and earlier are vulnerable to a denial-of-service (DoS) attack through improper handling of proxy headers. When Keycloak is configured to accept incoming proxy headers, it may accept non-IP values, such as obfuscated identifiers, without proper validation. This can lead to costly DNS resolution operations, which an attacker could exploit to tie up IO threads and potentially cause a denial of service. The attacker must have access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers. For Keycloak version 26, for successful exploitation includes: the realm must have SslRequired=EXTERNAL (the default), HTTP must be enabled, the instance must not be using a full hostname URL, access must come from behind a proxy (assuming the proxy overwrites the X-Forwarded-For header), and trusted proxies must not be set or must incor...

A vulnerability was found in the Keycloak-services package. If untrusted data is passed to the SearchQueryUtils method, it could lead to a denial of service (DoS) scenario by exhausting system resources due to a Regex complexity.

Debian Linux Security Advisory 5818-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

Ubuntu Security Notice 7124-1 - Andy Boothe discovered that the Networking component of OpenJDK 23 did not properly handle access under certain circumstances. An unauthenticated attacker could possibly use this issue to cause a denial of service. It was discovered that the Hotspot component of OpenJDK 23 did not properly handle vectorization under certain circumstances. An unauthenticated attacker could possibly use this issue to access unauthorized resources and expose sensitive information.

Debian Linux Security Advisory 5817-1 - Security issues were discovered in Chromium which could result in the execution of arbitrary code, denial of service, or information disclosure.
