CVE-2006-0323
CAN-2005-2922

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.

The following products are affected by one of more of the vulnerabilities:
* RealPlayer 10.5 (6.0.12.1040-1348)
* RealPlayer 10
* RealOne Player v2
* RealOne Player v1
