    CVE-2012-0390

    Published: 6 Jan 2012Last Modified: 10 Apr 2026

    Summary:

    Details: The DTLS implementation in GnuTLS 3.0.10 and earlier executes certain error-handling code only if there is a specific relationship between a padding length and the ciphertext size, which makes it easier for remote attackers to recover partial plaintext via a timing side-channel attack, a related issue to CVE-2011-4108.
