Researchers have discovered a weakness in the handling of CBC cipher suites in SSL, TLS and DTLS for RSA BSAFE Micro Edition Suite for all versions outside of 4.0.3 and 3.2.5. The Lucky Thirteen attack exploits timing differences arising during MAC processing. Vulnerable implementations do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the "Lucky Thirteen" issue.
