-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerability installations of RealNetworks RealPlayer. User interaction
is required to exploit this vulnerability in that the target must open a
malicious SHOUTcast Stream.

The specific flaw exists in the processing of the StreamTitle tag in a
SHOUTcast stream using the ICY protocol. A specially crafted string
supplied as the property for the title can result in a failed allocation
of heap memory. This then causes the freeing of critical pointers that
are subsequently used after freeing. Successful exploitation of this
vulnerability can lead to system compromise under the credentials of the
currently logged in user.

-- Vendor Response:
RealNetworks has issued an update to correct this vulnerability. More
