EUVD-2026-26926
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-2026-33846
GnuTLS DTLS handshake fragment reassembly (merge_handshake_packet) fails to enforce consistent message_length across fragments, enabling a heap-based out-of-bounds write when fragments with conflicting lengths are received. This remote, unauthenticated vulnerability can cause application crashes ...

CVE-2026-7776: Allocation of Resources Without Limits or Throttling
Boundary Community Edition and Boundary Enterprise “Boundary” workers are vulnerable to a denial-of-service condition during node enrollment TLS handshakes. An attacker with network access to the worker authentication listener may open a connection and delay or withhold the client certificate...
HashiCorp Boundary security vulnerability
HashiCorp Boundary is an open-source solution developed by HashiCorp in the United States. It enables secure, identity-based access for users across different environments to hosts and services. There are security vulnerabilities in versions of HashiCorp Boundary prior to 0.21.3, 0.20.3, and...
GnuTLS security vulnerabilities
GnuTLS is an open-source, free security communication library developed by GnuTLS that enables the implementation of SSL, TLS, and DTLS protocols. GnuTLS has a security vulnerability, which stems from the mergehandshakepacket function in the DTLS handshake reassembly logic not verifying the...

CVE-2026-33846: Improper Handling of Length Parameter Inconsistency
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...
Observability for Post-Quantum TLS Readiness: A Multi-Surface Evidence Framework
Post-quantum migration in Transport Layer Security TLS requires evidence-aware measurements that distinguish session negotiation, endpoint capability, certificate-chain evidence, and the provenance of missing observations. This distinction is essential under TLS 1.3 encryption, resumption, mutual...
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...
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...
SUSE CVE-2026-33845
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...
PT-2026-42452
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the t7xx port enum msg handler function where the modem-supplied port count field is used as a loop bound over port msg-data without verifying if the message buffer...
ALPINE-CVE-2026-3832
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...
