This update was imported from the openSUSE:Leap:15.1:Update update project.

These are all security issues fixed in the axel-2.17.10-1.6 package on the GA media of openSUSE Tumbleweed.

It was discovered that Axel did not properly verify the certificates for hostnames. An attacker could use this vulnerability to impersonate another server and obtain sensitive information.
