iDEFENSE Security Advisory 2007-05-10.3
Posted May 11, 2007

iDefense Security Advisory 05.10.07 - Remote exploitation of multiple buffer overflow vulnerabilities in Apple Inc.'s Darwin Streaming Proxy allows attackers to execute arbitrary code with the privileges of running service, usually root. Due to insufficient sanity checking, a stack-based buffer overflow could occur while trying to extract commands from the request buffer. The "is_command" function, located in proxy.c, lacks bounds checking when filling the 'cmd' and 'server' buffers. Additionally, a heap-based buffer overflow could occur while processing the "trackID" values contained within a "SETUP" request. If a request with more than 32 values is encountered, memory corruption will occur. iDefense has confirmed the existence of these vulnerabilities in Darwin Streaming Server 5.5.4 and Darwin Streaming Proxy 4.1. It is suspected that earlier versions are also vulnerable.
