Issue Overview:

The ConnectionExists function in lib/url.c in libcurl before 7.47.0 does not properly re-use NTLM-authenticated proxy connections, which might allow remote attackers to authenticate as other users via a request, a similar issue to CVE-2014-0015. (CVE-2016-0755)

Affected Packages:

curl

Run yum update curl to update your system.
