CVE-2026-54874

Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than the record itself requires. Impact summary: A peer can use a small amount of network traffic to make an OpenSSL DTLS endpoint retain a disproportionately large...

OpenSSL 1.0.2 < 1.0.2zr Vulnerability

The version of OpenSSL installed on the remote host is prior to 1.0.2zr. It is, therefore, affected by a vulnerability as referenced in the 1.0.2zr advisory. - Issue summary: Receiving a DTLS record for a future epoch while a handshake is in progress causes OpenSSL to buffer far more memory than...

Linux Distros Unpatched Vulnerability : CVE-2023-6937

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wolfSSL prior to 5.6.6 did not check that messages in one DTLS record do not span key boundaries. As a result, it was possible to combine DTLS messages using...

A null pointer denial of service vulnerability exists in the OpenSSL 'dtls1getrecord' function, which could be exploited by an attack...

Design/Logic Flaw

The dtls1bufferrecord function in ssl/d1pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service memory consumption via a large series of "future epoch" DTLS records that are buffered in a queue, aka "DTLS record buffer limitation bug."...
