CVE-2005-0611


Description:
Two 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 within the processing of WAV files can be exploited to cause a buffer overflow via a specially crafted WAV file.

2) A boundary error within the processing of SMIL files can be exploited to cause a stack-based buffer overflow via a specially crafted SMIL file.

Successful exploitation of the vulnerabilities allows execution of arbitrary code.

Solution:
Apply patches.

Patches are available via the "Check for Update" feature.
