crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

SUSE CVE-2026-7666

An issue was discovered in Django 6.0 before 6.0.6 and 5.2 before 5.2.15. django.core.mail.backends.smtp.EmailBackend in Django fails to prevent reuse of a partially-initialized connection after a failed STARTTLS handshake when failsilently=True, which allows on-path network attackers to read ema...

Traefik < 2.11.38 / 3.x < 3.6.9 Multiple Vulnerabilities

The version of Traefik installed on the remote macOS host is prior to 2.11.38 or 3.x prior to 3.6.9. It is, therefore, affected by multiple vulnerabilities: - A flaw exists in the ForwardAuth middleware due to the response body from the authentication server being read entirely into memory withou...

CVE-2026-44546

daphne before 4.2.2 reconstructs a raw HTTP request from Twisted's parsed headers and feeds it to autobahn for WebSocket handshake processing. Twisted does not treat \x0b, \x0c, \x1c, \x1d, \x1e, or \x85 as header line separators, but autobahn decodes header values to str and calls splitlines. An...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...

CVE-2026-37220

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2SETUPREQUEST is sent. The near-RT RIC assumes a mapping between SCTP association and E2 node always exists in the cleanup path and enforces this via assert. A remote unauthenticated attacker can crash the near-RT RIC port 36421...

Apache Airflow's EmailOperator and the underlying airflow.utils.email helpers established SMTP STARTTLS connections without verifying the remote certificate when the deployment used email smtpstarttls=True without email smtpssl. An attacker positioned between the worker and the configured SMTP...

qemu-kvm: VNC WebSocket handshake use-after-free

A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network acces...
