Overview

curl vulnerability

Releases

Packages

Details

It was discovered that curl did not enforce any restrictions when following
URL redirects. If a user or automated system were tricked into opening a URL to
an untrusted server, an attacker could use redirects to gain access to abitrary
files. This update changes curl behavior to prevent following “file” URLs after
a redirect.
