Debian Security Advisory 1738-1 – David Kierznowski discovered that libcurl, a multi-protocol file transfer library, when configured to follow URL redirects automatically, does not question the new target location. As libcurl also supports file:// and scp:// URLs – depending on the setup – an untrusted server could use that to expose local files, overwrite local files or even execute arbitrary code via a malicious URL redirect.
