Open SSL timing attack

Because of timing difference it's possible to distinguish between bad padding and a MAC verification error. It's also possible to recover RSA secret...

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...

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...

[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...

Vulnerability in OpenSSL

Dan Boneh and I have been researching timing attacks against software crypto libraries. Timing attacks are usually used to attack weak computing devices such as smartcards. We've successfully developed and mounted timing attacks against software crypto libraries running on general purpose PC's. W...

Vulnerability in OpenSSL CVE-2003-0147

CVE-2002-0507

An interaction between Microsoft Outlook Web Access OWA with RSA SecurID allows local users to bypass the SecurID authentication for a previous user via several submissions of an OWA Authentication request with the proper OWA password for the previous user, which is eventually accepted by OWA...

Three problems in OpenSSH's ssh-keysign

This is being posted to bugtraq in the interest of full disclosure. Originally sent to [email protected]. There are 3 problems we observed by inspection of OpenSSH's ssh-keysign: 1 Charles Hannum Since no blinding is done on the RSA calculations, ssh-keysign is effectively a fairly efficient...

CVE-2002-0507

CVE-2002-0507 describes an authentication bypass in Microsoft Outlook Web Access (OWA) when used with RSA SecurID. Local users could bypass SecurID for a previous user by submitting multiple OWA Authentication requests using the previous user’s password, which is eventually accepted by OWA. The N...
