unescaped URLs. A remote attacker could provide a specially crafted
URL that, when processed by an application using libcurl that handles
untrusted URLs, would possibly cause it to crash or, potentially,
execute arbitrary code. (CVE-2013-2174)
All running applications using libcurl must be restarted for the
update to take effect."
