RealPlayer IVR File Processing Two Vulnerabilities

Secunia ID	SA33810
CVE-ID	CVE-2009-0375, CVE-2009-0376
Release Date	10 Feb 2009
Last Change	22 Jan 2010
Criticality	Highly Critical Typically used for remotely exploitable vulnerabilities that can lead to system compromise. Successful exploitation does not normally require any interaction but there are no known exploits available at the time of disclosure. Such vulnerabilities can exist in services like FTP, HTTP, and SMTP or in client systems like email programs or browsers.
Solution Status	Vendor Patch
Software	RealPlayer 11.x
Where	From remote "From remote" describes other vulnerabilities where the attack vector doesn't require access to the system or a local network. This category covers services that are acceptable to expose to the Internet (e.g. HTTP, HTTPS, SMTP). It also covers client applications used on the Internet and certain vulnerabilities where it is reasonable to assume that a security conscious user can be tricked into performing certain actions.
Impact	DoS (Denial of Service) This includes vulnerabilities ranging from excessive resource consumption (e.g. causing a system to use a lot of memory) to crashing an application or an entire system. System access This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.
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	Update to the newest RealPlayer version. Windows: http://client-software.real.com/free/windows/installer/stubinst/stub/rp12/R51GSEC/RealPlayerSPGold.exe Max OS X: Upgrade to the latest version of RealPlayer 11. http://www.real.com/mac/realplayer Linux: http://www.real.com/linux
