-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : openssl SUMMARY : Several vulnerabilities in the OpenSSL library DATE : 2001-08-30 16:11:00 ID : CLA-2001:418 RELEVANT RELEASES : 4.0, 4.0es, 4.1, 4.2, 5.0, prg graficos, ecommerce, 5.1, 6.0, 7.0 - ------------------------------------------------------------------------- DESCRIPTION OpenSSL is a library providing several crypto and digital certificate handling functions. Several vulnerabilities have been addressed in newer versions of this library: 1. OpenSSL now avoids using environment variables when running as root; 2. The result of RSA-CRT is now checked to reduce the possibility of deducing the private key from an incorrectly calculated signature; 3. Changes to prevent Bleichenbacher's DSA attack; 4. OpenSSL now zeroes the premaster secret after deriving the master secret in DH ciphersuites; 5. Fix for a vulnerability in the pseudo random number generator which allowed an attacker to predict the internal state of the PRNG and thus predict future PRNG output. The first four vulnerabilities have been addressed in the 0.9.6a version of the library and affect Conectiva Linux <= 6.0 only, while the last one was fixed with the 0.9.6b release and affects Conectiva Linux 7.0 and earlier. The packages available through this update have been patched to fix all these vulnerabilities. Thanks to the OpenSSL team for releasing the new versions and to Nalin Dahyabhai from Redhat for providing patches for older versions. SOLUTION All users should upgrade the OpenSSL library. After the update, programs which use the library, such as apache and openssh, should be restarted. IMPORTANT: updated packages for Conectiva Linux 4.0 and 4.0es are not yet available.
