Cryptographic libraries and applications do not adequately defend against timing attacks

Overview Cryptographic libraries and applications do not provide adequate defense against a side-channel timing attack against RSA private keys. Such an attack has been shown to be practical using currently available hardware on systems and networks with sufficiently low variance in latency...

CVE-2003-0131

The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS 1 v1.5 padding that cause OpenSSL to leak...

CVE-2003-0131

CVE-2003-0131 (and related CVE-2003-0147) affect OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a. The issue enables remote attackers to perform an unauthorized RSA private key operation via a Klima-Pokorny-Rosa–style Bleichenbacher attack using many SSL/TLS connections with PKCS#1 v1.5 padding, lea...

[OpenSSL Advisory] Klima-Pokorny-Rosa attack on PKCS #1 v1.5 padding

OpenSSL Security Advisory 19 March 2003 Klima-Pokorny-Rosa attack on RSA in SSL/TLS =========================================== Czech cryptologists Vlastimil Klima, Ondrej Pokorny, and Tomas Rosa have come up with an extension of the "Bleichenbacher attack" on RSA with PKCS 1 v1.5 padding as used...

Vulnerability in OpenSSL CVE-2003-0131

The SSL and TLS components allowed remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS 1 v1.5 padding that caused OpenSSL to leak information regarding the relationship between...

CVE-2003-0147

OpenSSL does not use RSA blinding by default, which allows local and remote attackers to obtain the server's private key by determining factors using timing differences on 1 the number of extra reductions during Montgomery reduction, and 2 the use of different integer multiplication algorithms...

CVE-2003-0147

OpenSSL CVE-2003-0147 is documented as a timing-attack vulnerability where RSA private-key material can be inferred because RSA blinding is not used by default. The vulnerability arises from timing differences during Montgomery reductions and differing multiply routes (Karatsuba vs. normal), enab...

[ADVISORY] Timing Attack on OpenSSL

OpenSSL v0.9.7a and 0.9.6i vulnerability ---------------------------------------- Researchers have discovered a timing attack on RSA keys, to which OpenSSL is generally vulnerable, unless RSA blinding has been turned on. Typically, it will not have been, because it is not easily possible to do so...
