CVE-2026-55953

A flaw was found in the Erlang/OTP ssl client. This vulnerability allows an on-path attacker to bypass server authentication in TLS 1.2 and earlier and DTLS connections. By tricking the client into accepting an unoffered anonymous cipher suite, the attacker can complete the handshake without a...

CVE-2026-55737

A flaw was found in Erlang OTP. A remote attacker can exploit a vulnerability in the Erlang external term format ETF decoder by providing a specially crafted binary to the binarytoterm/1 function. This manipulation of data types during processing can corrupt the system's memory, leading to an...

CVE-2026-59251

A flaw was found in Erlang/OTP's publickey application. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted X.509 certificate chain during a Transport Layer Security TLS handshake. This causes the certificate path validation process to consume excessiv...

CVE-2026-54890

A flaw was found in Erlang/OTP. A remote attacker can exploit an integer underflow vulnerability in the External Term Format ETF decoder, specifically within the binarytoterm function. By sending a specially crafted ETF payload with a zero-length BITBINARYEXT tag, the attacker can trigger an...

Linux Distros Unpatched Vulnerability : CVE-2026-59248

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Allocation of resources without limits vulnerability in ninenines cowlib allows an unauthenticated remote HTTP/2 or HTTP/3 peer to exhaust memory on the...

cowboy: Cowboy: Denial of Service via HTTP/1.1 duplicate header names

A flaw was found in Cowboy. An unauthenticated remote attacker can exploit this vulnerability by sending multiple HTTP/1.1 header lines with the same name. This bypasses the maxheaders limit, causing the connection process memory to grow uncontrollably. This can lead to memory exhaustion and a...

CVE-2026-65624 Cowboy HTTP/1.1 max_headers Bypass via Duplicate Header Names Enables Memory Exhaustion

Allocation of Resources Without Limits or Throttling vulnerability in ninenines cowboy allows an unauthenticated remote attacker to exhaust connection process memory over HTTP/1.1. The HTTP/1.1 handler in cowboyhttp enforces the maxheaders limit by counting the number of distinct header names in ...

CVE-2026-65624

The CVE affects the Cowboy HTTP/1.1 handler. The root cause is a per-request header handling flaw: when a request uses repeated header names, values are concatenated into a single binary under one map key, so the max_headers limit never increases and the total header block can grow without bound....

Allocation of Resources Without Limits or Throttling vulnerability in ninenines cowboy allows an unauthenticated remote attacker to exhaust connection process memory over HTTP/1.1. The HTTP/1.1 handler in cowboyhttp enforces the maxheaders limit by counting the number of distinct header names in ...

CVE-2026-59248

CVE-2026-59248 affects cowlib (2.0.0–2.19.0). The HPACK/QPACK dec_big_int/3 decoder has no limit on continuation octets or resulting bit width, causing unbounded memory allocation during decoding and potential memory exhaustion DoS when handling untrusted HTTP/2/3 peers. A single maximal HPACK in...

CVE-2026-59248 Unbounded HPACK/QPACK prefixed-integer decoding in Cowlib causes memory-exhaustion DoS

Allocation of resources without limits vulnerability in ninenines cowlib allows an unauthenticated remote HTTP/2 or HTTP/3 peer to exhaust memory on the vulnerable server or client and cause a denial of service. The HPACK and QPACK prefixed-integer decoder cowhpackcommon:decbigint/3 in...
