Title

Gnutls: gnutls: information disclosure via timing side-channel in pkcs#7 padding removal

Summary

A flaw was found in gnutls. The PKCS#7 padding check, performed during decryption, was not constant-time. This timing side-channel could allow a remote attacker to potentially leak sensitive information about the padding bytes through observable timing differences. This vulnerability is a form of information disclosure.
