CVE-2011-4108

Publication date 5 January 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack.
