Rated as : Moderate Risk

Technical Description
Two vulnerabilities have been identified in Perlbal, which could be exploited by attackers to cause a denial of service or gain knowledge of sensitive information.
The first issue is caused by errors in the "lib/Perlbal/ClientProxy.pm" file when processing zero byte chunked uploads while buffered uploads are enabled, which could be exploited by attackers to crash an affected application, creating a denial of service condition.
The second vulnerability is caused by an input validation error in the "_serve_request_multiple()" [lib/Perlbal/ClientHTTPBase.pm] function when processing user-supplied requests, which could be exploited to conduct a single upward directory traversal attack and disclose sensitive information.
