RealNetworks Real Player Predictable Temporary File Remote Code Execution
ZDI-11-076: February 8th, 2011
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of RealNetworks RealPlayer. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.
The flaw exists within the temporary file naming scheme used for storage of
references to Real Media files. This easily predictable temporary filename can
be brute forced and used in combination with the OpenURLinPlayerBrowser
function available in classid:FDC7A535-4070-4B92-A0EA-D9994BCC0DC5 to execute
the file. A remote attacker can exploit this vulnerability to execute
arbitrary code under the context of the browser.
RealNetworks has issued an update to correct this vulnerability. More details
