Debian Security Advisory

DSA-1738-1 curl -- arbitrary file access

Date Reported:

11 Mar 2009

Affected Packages:

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 518423.
In the Bugtraq database (at SecurityFocus): BugTraq ID 33962.
In Mitre's CVE dictionary: CVE-2009-0037.

More information:

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.

Fixed in:

Debian GNU/Linux 4.0 (etch)
