JanaServer2 contains a flaw that may allow a remote denial of service. The issue is due to an error in "pna-proxy" module when handling real player requests. By specifing a data block size bigger than the data really sent in a real player request, a remote attack can cause a endless loop and crash the server, resulting in a loss of availability.


Location: Remote / Network Access
Attack Type: Input Manipulation
Impact: Loss of Confidentiality, Loss of Availability
Exploit: Exploit Public


Upgrade to version 2.4.5 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
