CRITICAL:
Moderately critical

DESCRIPTION:
Luigi Auriemma has reported a vulnerability in Netembryo, which can
be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a NULL pointer dereference error
within the "Url_init()" function in utils/url.c. This can be
exploited to crash an application using the library via a URL
containing a "/:" sequence.

The vulnerability is reported in version 0.0.4. Other versions may
also be affected.

SOLUTION:
The vendor will reportedly fix the vulnerability in the next version.
Do not use the vulnerable function to process untrusted input.
