Overview
Affected versions of this package are vulnerable to Integer Underflow (Wrap or Wraparound) via the ssl_DecodePacket process. An attacker can cause a heap buffer overflow and application crash by injecting a malformed TLS Application Data record that is shorter than the required explicit IV plus authentication tag, resulting in an integer underflow and subsequent out-of-bounds access during AEAD decryption routines. This can be triggered remotely by an unauthenticated attacker through crafted network traffic.
