CVE-2012-0390

Publication date 6 January 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
