Description:
Luigi Auriemma has reported two vulnerabilities in JanaServer, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) An error in the "http-server" module can be exploited to cause a vulnerable server to consume a large amount of CPU resources by sending a specially crafted HTTP request containing a lot of "%'"characters to port 2506.

2) An error in the handling of Real Player requests in the "pna-proxy" module can be exploited to cause a vulnerable server to stop responding by sending multiple requests with malformed data block sizes to port 1090.

The vulnerabilities have been reported in version 2.4.4. Other versions may also be affected.

Solution:
Update to version 2.4.5.
