[Full-Disclosure] GnuPG's ElGamal signing keys compromised

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 GnuPG's ElGamal signing keys compromised ========================================== Summary ======= Phong Nguyen identified a severe bug in the way GnuPG creates and uses ElGamal keys for signing. This is a significant security failure which can lead ...

ElGamal sign+encrypt keys created by GnuPG can be compromised

Any ElGamal sign+encrypt keys created by GnuPG contain a cryptographic weakness that may allow someone to obtain the private key. These keys should be considered unusable and should be revoked. The following summary was written by Werner Koch, GnuPG author: Phong Nguyen identified a severe bug in...

security flaw

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...

DEBIAN-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...

[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...

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: Undefined Security Weakness

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...

Vulnerability in OpenSSL CVE-2003-0147

RSA blinding was not enabled by default, which could allow local and remote attackers to obtain a 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...
