CVE-2016-0755  (opens in a new tab)
CWE-287  (opens in a new tab)

How to fix?

Upgrade Amazon-Linux:2018.03 curl to version 0:7.40.0-8.54.amzn1 or higher.
This issue was patched in ALAS-2016-652.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

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.
