netty-handler: Netty: Denial of Service due to eager buffer allocation in TLS handshake

A flaw was found in Netty, a network application framework. A remote attacker can exploit this vulnerability by sending a crafted TLS Transport Layer Security ClientHello message. This can lead to an eager allocation of a large memory buffer, causing a Denial of Service DoS due to excessive memor...

GHSA-X2QC-CMH9-F4HF Deno: Denial of service via non-ASCII bytes in WebSocket response headers

Summary A Deno program that opens a client WebSocket connection could be crashed by the remote server. While handling the WebSocket handshake response, Deno parsed the Sec-WebSocket-Protocol and Sec-WebSocket-Extensions response headers in a way that assumed their bytes were always printable ASCI...

Unchecked Input for Loop Condition

Overview Affected versions of this package are vulnerable to Unchecked Input for Loop Condition in the SSHMSGEXTINFO handler during the initial handshake process. An attacker can cause the client application to become unresponsive by sending a crafted extension count value that triggers an infini...

eclipse-vertx/vert.x: eclipse-vertx/vert.x: Denial of Service via TLS handshake with wildcard server name

A flaw was found in eclipse-vertx/vert.x. A remote attacker can exploit this vulnerability by performing a Transport Layer Security TLS handshake and presenting a server name extension with a server wildcard name. This can lead to a denial of service DoS condition, impacting the availability of t...

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,...

CVE-2025-71261

An attacker with network-level access between the SUSE Virtualization and Rancher Manager in SUSE Harvester before 1.8.0 could interfere with the TLS handshake and abuse it to bypass TLS as a security control...

gnutls: gnutls: Security bypass allows acceptance of revoked server certificates via crafted OCSP response

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol OCSP response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabl...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

gnutls: GnuTLS: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly

A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

CVE-2025-71261

The CVE-2025-71261 issue affects the SUSE Virtualization (Harvester) Rancher integration registration client, specifically the cluster-registration-url path. The root cause is an insecure TLS setup that fails to verify the remote server’s certificate, enabling MITM between SUSE Virtualization and...
