TITLE:
RealPlayer IVR File Processing Two Vulnerabilities

SECUNIA ADVISORY ID:
SA33810

VERIFY ADVISORY:
http://secunia.com/advisories/33810/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
RealPlayer 11.x
http://secunia.com/advisories/product/16937/

DESCRIPTION:
Some vulnerabilities have been reported in RealPlayer, which can be
exploited by malicious people to compromise a vulnerable system.

1) An input validation error within the processing of Internet Video
Recording (IVR) files can be exploited to cause a memory corruption
when a specially crafted IVR file is viewed.

2) An unspecified error within the processing of IVR files can be
exploited to write a NULL-byte to an arbitrary memory address via an
overly long file name length value within a specially crafted IVR
file.

Successful exploitation potentially allows execution of arbitrary
code e.g. when a user visits a malicious web page.

SOLUTION:
According to the reporter this is fixed in the latest version of
RealPlayer 11.
