CVE-2012-0390

Severity CVSS v4.0:
Pending analysis
Type:
CWE-310 Cryptographic Issues
Publication date:

Last modified:

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.
