CVE-2024-23573
HCL Aftermarket EPC is vulnerable to attack since the Application is vulnerable to Lucky 13. that makes the SS LLUCKY13 possible affects the TLS1.1and 1.2 and DTLS1.0 or 1.2 implementations . It also affects previous versions such as SSL3.0 and TLS1.0. This can also be considered a type of...
JLSEC-2026-671
wolfSSL before 5.4.0 allows remote attackers to cause a denial of service via DTLS because a check for return-routability can be skipped...
The vulnerability of the DTLS implementation of the GnuTLS cryptographic library allows a attacker to induce a service failure.
The vulnerability of the DTLS protocol implementation of the GnuTLS cryptographic library is related to unpredictable behavior of functions due to inconsistencies in parameter values. Exploiting this vulnerability could allow a malicious actor to cause service failures remotely...
CVE-2026-55950 DTLS listener crash via race condition in dtls_packet_demux causes denial of service for all sessions
Time-of-check Time-of-use TOCTOU race condition vulnerability in Erlang/OTP ssl dtlspacketdemux module allows an unauthenticated remote attacker to crash all active DTLS sessions on a listener. A DTLS server listener uses a single shared dtlspacketdemux genserver process to route incoming UDP...
CVE-2026-55950
This CVE (CVE-2026-55950) describes a TOCTOU race in Erlang/OTP ssl (dtls_packet_demux.erl) where a DTLS listener’s shared demux process can be crashed by an unauthenticated remote attacker sending rapid ClientHello datagrams from the same source IP/port. The race in the internal gb_trees store l...
CVE-2026-54887 DTLS server cookie bypass during startup window due to empty initial cookie secret
Use of Default Cryptographic Key vulnerability in Erlang/OTP ssl DTLS server allows predictable DTLS cookie computation during the startup window, enabling source address verification bypass. On DTLS server startup, dtlsserverconnection:initialhello/3 initializes previouscookiesecret to the empty...

gnutls: gnutls: Denial of Service via DTLS packet reordering vulnerability
A flaw was found in gnutls. A remote attacker could exploit an issue in the Datagram Transport Layer Security DTLS packet reordering logic. The comparator function, responsible for ordering DTLS packets by sequence numbers, did not correctly handle packets with duplicate sequence numbers. This...

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...
RHEL 8 : gnutls and libtasn1 (RHSA-2026:30849)
The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:30849 advisory. The gnutls packages provide the GNU Transport Layer Security GnuTLS library, which implements cryptographic algorithms and protocols such a...
