Description

Versions of OpenSSL software shipped with JUNOS releases built prior to March 13, 2003 do not perform a MAC checksum calculation on packets that contain incorrect block cipher padding. An attacker can detect the difference in the amount of time required for reporting incorrect padding errors and reporting MAC checksum verification errors. Being able to distinguish between the two types of errors can aid an attacker in devising more effective attacks against certain encryption algorithms.
