code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
(CVE-2016-9586)
Even Rouault discovered that curl incorrectly handled large file names when

to crash, resulting in a denial of service, or possibly obtain sensitive
memory contents. (CVE-2017-1000100)
Brian Carpenter and Yongji Ouyang discovered that curl incorrectly handled
numerical range globbing. A remote attacker could use this issue to cause
curl to crash, resulting in a denial of service, or possibly obtain
