Description

Several vulnerabilities were discovered in cURL, an URL transfer library:

CVE-2016-5419 Bru Rom discovered that libcurl would attempt to resume a TLS session even if the client certificate had changed.

CVE-2016-5420 It was discovered that libcurl did not consider client certificates when reusing TLS connections.

CVE-2016-5421 Marcelo Echeverria and Fernando Munoz discovered that libcurl was vulnerable to a use-after-free flaw.
