Ubuntu: openssl-blacklist update
LinuxSecurity.com: USN-612-3 addressed a weakness in OpenSSL certificate and key generation in OpenVPN by introducing openssl-blacklist to aid in detecting vulnerable private keys. This update enhances the openssl-vulnkey tool to check X.509 certificates as well, and provides the corresponding update for Ubuntu 6.06. While the OpenSSL in Ubuntu 6.06 was not vulnerable, openssl-blacklist is now provided for Ubuntu 6.06 for checking certificates and keys that may have been imported on these systems.

Solaris v Ubuntu using OpenSSL paste problem

Hello, I hope this means something to someone. I have an odd problem that just started happening recently. I am not the system admin, so I don't have full info on any changes to the system lately.

ssl_ctx_add_extra_chain_cert

SSL_CTX_add_extra_chain_cert(3) 				      OpenSSL					   SSL_CTX_add_extra_chain_cert(3)

NAME

       SSL_CTX_add_extra_chain_cert - add certificate to chain

SYNOPSIS

	#include <openssl/ssl.h>

	long SSL_CTX_add_extra_chain_cert(SSL_CTX ctx, X509 *x509)

DESCRIPTION

       SSL_CTX_add_extra_chain_cert() adds the certificate x509 to the certificate chain presented together with the certificate. Several certifi-
       cates can be added one after the other.

NOTES

       When constructing the certificate chain, the chain will be formed from these certificates explicitly specified. If no chain is specified,
       the library will try to complete the chain from the available CA certificates in the trusted CA storage, see SSL_CTX_load_verify_loca-
       tions(3).

RETURN VALUES

       SSL_CTX_add_extra_chain_cert() returns 1 on success. Check out the error stack to find out the reason for failure otherwise.
