For further product information on the TippingPoint IPS: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on systems with vulnerable installations of the RealNetworks RealPlayer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists in RealPlayer's parsing of SWF files. The SWF rendering DLL RealPlayer uses fails to properly handle malformed record headers leading to an exploitable overflow. An attacker could exploit this vulnerability using an ActiveX control {CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA} and embedding the malicious swf file in the page or by convincing an affected user to directly open a SWF file using RealPlayer. - -- Vendor Response: RealNetworks has issued an update to correct this vulnerability. More details can be found at: http://service.real.com/realplayer/security/10252007_player/en/ - -- Disclosure Timeline: 2007.01.17 - Vulnerability reported to vendor 2007.02.15 - Digital Vaccine released to TippingPoint customers 2007.10.25 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by an anonymous researcher. - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, a division of 3Com, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.

For further product information on the TippingPoint IPS: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute code on vulnerable installations of RealPlayer. User interaction is required in that a user must open a malicious .pls file or visit a malicious web site. The specific flaw exists during the parsing of corrupted playlist files. Malicious corruption causes RealPlayer to call into a static heap address which can be leveraged by an attacker resulting in arbitrary code execution under the context of the logged in user. - -- Vendor Response: RealNetworks has issued an update to correct this vulnerability. More details can be found at: http://service.real.com/realplayer/security/10252007_player/en/ - -- Disclosure Timeline: 2007.03.09 - Vulnerability reported to vendor 2007.04.26 - Digital Vaccine released to TippingPoint customers 2007.10.25 - Coordinated public release of advisory - -- Credit: This vulnerability was discovered by an anonymous researcher. - -- About the Zero Day Initiative (ZDI): Established by TippingPoint, a division of 3Com, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities.

For further product information on the TippingPoint IPS: http://www.tippingpoint.com - -- Vulnerability Details: This vulnerability allows remote attackers to execute code on vulnerable installations of RealPlayer. User interaction is required in that a user must open a malicious .ra/.ram file or visit a malicious web site. The specific flaw exists during the parsing of files with improperly defined size field in the RA header. Specifying a large unsigned value data can trigger a heap corruption and further result in arbitrary code execution under the context of the logged in user. - -- Vendor Response: RealNetworks has issued an update to correct this vulnerability.
