Description

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.

Affected products

[UNKNOWN] gnutls: through 3.0.10; 2.2.4, 2.2.5, 2.4.0, 2.4.1, 2.4.2, 2.4.3 (+49)
