Curl Update

There's an issue when e.g. updating Joomla Plugins, curl cannot verify peer certificate because of an outdated CA Bundle. See here: https://github.com/joomla-extensions/weblinks/issues/79

To resolve and have an up-to-date CA-Certificate Bundle (and CURL library), it's necessary to update the Curl package. This can be done like this:

Prerequisites

OpenSSL Update must be done before as described here: http://syswiki.internet-license.net/index.php?title=Openssl_patch

Package "customopenssl" must be isntalled. Check with:

rpm -qa customopenssl

Update

Copy the following RPMS to the Sever:

scp libcurl4-7.44.0-1.1.x86_64.rpm tuxNN:/usr/local/src/rpm/openssl_upgrade
scp curl-7.44.0-1.1.x86_64.rpm tuxNN:/usr/local/src/rpm/openssl_upgrade
scp curl-ca-bundle-7.44.0-1.1.x86_64.rpm tuxNN:/usr/local/src/rpm/openssl_upgrade

(only updating the ca bundle would not help because current curl cannot cope with hashing algorithms within the new bundle)

Then update packages on the server:

cd /usr/local/src/rpm/openssl_upgrade
rpm -Uvh libcurl4-7.44.0-1.1.x86_64.rpm curl-7.44.0-1.1.x86_64.rpm curl-ca-bundle-7.44.0-1.1.x86_64.rpm
