Upgrade Centos:6 libcurl to version 0:7.19.7-37.el6_4 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libcurl package and not the libcurl package as distributed by Centos.
See How to fix? for Centos:6 relevant fixed versions and status.
Heap-based buffer overflow in the curl_easy_unescape function in lib/escape.c in cURL and libcurl 7.7 through 7.30.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string ending in a "%" (percent) character.
