One of the openSSL vulnerabilities is: CVE-2013-0169:
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, , 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. All versions of OpenSSL are affected including 1.0.1c, 1.0.0j and 0.9.8x Affected users should upgrade to OpenSSL 1.0.1d, 1.0.0k or 0.9.8y we use DTLS 1.0 protocol. Does anyone know of any setting in openssl configuration that can be tweaked to mitigate this vulnerability? E.g. a setting to not allow use of algorithms with CBC etc.? Regards, Alok
