Summary

The remote host is missing an update to curl announced via advisory DSA 1738-1.

Insight

Insight

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. This update introduces a new option called CURLOPT_REDIR_PROTOCOLS which by default does not include the scp and file protocol handlers. For the oldstable distribution (etch) this problem has been fixed in version 7.15.5-1etch2. For the stable distribution (lenny) this problem has been fixed in version 7.18.2-8lenny2. For the unstable distribution (sid) this problem has been fixed in version 7.18.2-8.1. We recommend that you upgrade your curl packages.
