A flaw was found in Erlang OTP's Erlang Port Mapper Daemon (epmd). An unauthenticated remote attacker can exploit an improper handling of exceptional conditions in the do_accept function. By exhausting connection slots through holding numerous TCP connections open and periodically sending data, the attacker can force epmd to terminate, leading to a permanent Denial of Service (DoS). This can further impact system stability on certain Linux distributions by causing related services to fail permanently.

Threats
Impact Important

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 `binary_to_term` function. By sending a specially crafted ETF payload with a zero-length `BIT_BINARY_EXT` tag, the attacker can trigger an unsigned integer underflow. This leads to an attempt to allocate an excessively large amount of memory, causing the Erlang Virtual Machine (VM) to crash, resulting in a denial of service. This VM-level crash cannot be handled by standard Erlang error mechanisms.

Threats
Impact Important

A flaw was found in Erlang/OTP's `public_key` 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 excessive central processing unit (CPU) and memory resources, leading to a denial of service (DoS) by crashing the Erlang Virtual Machine (VM).

CWE-770 - Allocation of Resources Without Limits or Throttling
