Several security related problems have been discovered in webcalendar,
a PHP based multi-user calendar.  The Common Vulnerabilities and
Exposures project identifies the following vulnerabilities:

CVE-2005-3949

    Multiple SQL injection vulnerabilities allow remote attackers to
    execute arbitrary SQL commands.

CVE-2005-3961

    Missing input sanitising allowas an attacker to overwrite local
    files.

CVE-2005-3982

    A CRLF injection vulnerability allows remote attackers to modify
    HTTP headers and conduct HTTP response splitting attacks.

The old stable distribution (woody) does not contain webcalendar packages.

For the stable distribution (sarge) these problems have been fixed in
version 0.9.45-4sarge3.

For the unstable distribution (sid) these problems have been fixed in
version 1.0.2-1.

We recommend that you upgrade your webcalendar package.
