- 7.5 High severity
Red Hat Enterprise Linux 10: Uncontrolled Resource Consumption
A denial-of-service flaw was found in gnome-remote-desktop. An unauthenticated remote attacker can open RDP connections without completing the handshake and retain the connection-throttling slots indefinitely because no pre-authentication handshake deadline is
- 9.9 Critical severity
Red Hat Ansible Automation Platform 2.4 for…: Improper Neutralization of Argument Delimiters in a Command
A flaw was found in Red Hat Ansible Automation Platform's automation- controller. The Project scm_url field is not validated against values that begin with a dash and is stored and passed verbatim to the git SCM module. Because the module runs git ls-remote wi

- 8.5 High severity
Red Hat Ansible Automation Platform 2.7: Missing Authorization
CopyAPIView (awx/awx/api/generics.py:873) sets permission_classes = (IsAuthenticated,), so DRF's get_object() performs no object-level RBAC. The get() handler (lines 988–991) explicitly guards with request.user.can_access(obj._class_, 'read', obj) — but post()
- 7.3 High severity

- 8.8 High severity
Red Hat Enterprise Linux 10: Improper Limitation of a Pathname to a Restricted Directory
A malicious or compromised Flatpak repository can write attacker-controlled content to arbitrary locations on the host filesystem via extract_extra_data(). On system installs, the write happens as root. Two issues combine: `files/extra` is resolved via path op
- 7.8 High severity
Red Hat Enterprise Linux 10: Incorrect Authorization
A flaw was found in sudo. When sudoers rules use NOTBEFORE or NOTAFTER time-based access restrictions with timestamps that omit the trailing 'Z' timezone indicator, the time evaluation relies on the TZ environment variable inherited from the calling user. Beca

- 9.3 Critical severity
Red Hat OpenShift Container Platform 4.12: Server-Side Request Forgery
A flaw was found in the OpenShift console. Unauthenticated access to the `/api/devfile/` and `/api/devfile/samples/` endpoints allows a remote attacker to send crafted devfile payloads. This can lead to Server-Side Request Forgery (SSRF), where the console pod
- 7.5 High severity
Red Hat Enterprise Linux 10: Allocation of Resources Without Limits or Throttling
A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the `cockpit-tls` service. This forces the service to create an unbounded number of detached thread
- 7.5 High severity
Red Hat build of Apache Camel for Spring Boot 4: Improper Neutralization of CRLF Sequences
A flaw was found in Netty netty-codec-smtp. The component does not properly validate Carriage Return (CR) and Line Feed (LF) characters in the SMTP command-name field. A remote attacker, if an application routes untrusted input into this field, can embed CR/LF

Red Hat Build of Apache Camel 3.33.3.SP2: Inconsistent Interpretation of HTTP Requests
A flaw was found in Netty. A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prior
- 7.5 High severity
A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending…
A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/2 or HTTP/3 Extended CONNECT requests. Netty's HTTP-object conversion path incorrectly processes these requests as regular HTTP/1.1 CONNECT requests
- 7.5 High severity
A flaw was found in Netty's HTTP/2 codec.

A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service (DoS)
- 7.5 High severity
A flaw was found in Netty's WebSocketServerExtensionHandler.
A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-con
- 7.5 High severity
A flaw was found in the Netty STOMP codec.
A flaw was found in the Netty STOMP codec. A remote attacker could send a specially crafted STOMP frame with a content-length header exceeding the maximum integer value. This integer truncation vulnerability could lead to an infinite decode loop, causing a Den

Red Hat Build of Apache Camel 3.33.3.SP2: Allocation of Resources Without Limits or Throttling
A flaw was found in Netty's HttpServerCodec. A remote, unauthenticated attacker can exploit this vulnerability by pipelining HTTP/1.1 requests on a single connection and withholding reads. This action causes the methodOverflowQueue to grow without limit, leadi
- 7.5 High severity
Red Hat Build of Apache Camel 3.33.3.SP2: Allocation of Resources Without Limits or Throttling
A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAX_VALUE and the handler provides no API to change it. A remote peer can open a SPDY connection
- 7.5 High severity
