CVE-2026-92853

The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to 0xFFFFFFFF, which makes the bounds check that follows...

CVE-2026-92843

A missing bounds check in the TLS 1.3 Certificate-message parser of NetX Secure lets a malicious TLS 1.3 server trigger an unsigned-integer underflow and a subsequent heap out-of-bounds read in any peer that processes a remote Certificate message. It is reachable pre-authentication, during the...

CVE-2026-92853

The NetX Secure TLS 1.3 Certificate-message parser is vulnerable to an out-of-bounds read due to an integer underflow . The parser decrements the message length to skip a context byte without verifying if a byte exists; a zero-length Certificate message causes the unsigned length to wrap to 0xFFF...

CVE-2026-92853 Out-of-bounds Read via a Zero-length TLS 1.3 Certificate Message in NetX Secure

The TLS 1.3 Certificate-message parser in NetX Secure decrements the message length to skip a context byte without first establishing that the message has a byte to skip. A zero-length Certificate message therefore wraps the unsigned length to 0xFFFFFFFF, which makes the bounds check that follows...

JLSEC-2026-260 Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large...

Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. Impact summary: An attacker can cause per-connection memory allocations of up to approximately 22 MiB and...

openssl: OpenSSL: Denial of Service due to excessive memory allocation in TLS 1.3 certificate compression

A flaw was found in OpenSSL. A remote attacker can exploit this vulnerability by sending a specially crafted CompressedCertificate message during the TLS 1.3 handshake. This can cause excessive per-connection memory allocations, leading to resource exhaustion and a Denial of Service DoS for...

DEBIAN-CVE-2022-25638

In wolfSSL before 5.2.0, certificate validation may be bypassed during attempted authentication by a TLS 1.3 client to a TLS 1.3 server. This occurs when the sigalgo field differs between the certificateverify message and the certificate message...

Internet Bug Bounty: Certificate message OOB reads (CVE-2016-6306)

In OpenSSL 1.0.2 and earlier some missing message length checks can result in OOB reads of up to 2 bytes beyond an allocated buffer. There is a theoretical DoS risk but this has not been observed in practice on common platforms. The messages affected are client certificate, client certificate...
