A vulnerability in OpenSSL could allow an unauthenticated, remote attacker to conduct a cryptographic attack against a targeted system.
The vulnerability exists because the ChaCha20-Poly1305 Authenticated Encryption with Associated Data (AEAD) cipher used by the affected software could allow a long nonce to be used during an encryption operation. An attacker could exploit this vulnerability by sending a request that submits malicious input to the targeted system. A successful exploit could allow the attacker to conduct an attack that could impact the integrity and confidentiality of the affected application.
OpenSSL has confirmed the vulnerability and released software updates.
