'Name' => 'RealNetworks RealPlayer SMIL Buffer Overflow',
|
|
'Description' => %q{
|
|
This module exploits a stack buffer overflow in RealNetworks RealPlayer 10 and 8.
|
|
By creating a URL link to a malicious SMIL file, a remote attacker could
|
|
overflow a buffer and execute arbitrary code.
|
|
When using this module, be sure to set the URIPATH with an extension of '.smil'.
|
|
This module has been tested with RealPlayer 10 build 6.0.12.883 and RealPlayer 8
|
|
build 6.0.9.584.
