DESCRIPTION:
Some vulnerabilities have been reported in various RealNetworks
products, which can be exploited by malicious people to compromise a
user's system.

1) A boundary error when processing SWF files can be exploited to
cause a buffer overflow. This may allow execution of arbitrary code
on the user's system.

2) A boundary error within the handling of web pages can be exploited
via a specially crafted web page on a malicious server to cause a
heap-based buffer overflow. This may allow execution of arbitrary
code on the user's system.

3) A boundary error in the processing of MBC files can be exploited
to cause a buffer overflow. This may allow execution of arbitrary
code on the user's system.

A weakness when executing other programs is caused due to incorrect
use of the "CreateProcess()" API. This may allow execution of an
arbitrary program on the system, if this can be placed in the program
path.

vulnerabilities:
* RealPlayer 10.5 (6.0.12.1040-1348)
