Internet Security Systems Protection Alert Date: 03/28/06
Title: RealNetworks RealPlayer chunked Transfer-Encoding buffer overflow
Multiple versions of RealNetworks RealPlayer and RealOne Player are vulnerable to a heap-based buffer overflow, caused by improper handling of chunked Transfer-Encoded data. A remote attacker could create a specially-crafted Web page containing embedded object tags that launch an affected version of RealPlayer or RealOne Player. If a victim could be persuaded to view the malicious page, the attacker could overflow a buffer and execute arbitrary code on the victim's system.
Compromise of the operating system can lead to exposure of confidential information, loss of productivity, and further network compromise. Successful exploitation of this vulnerability could be used to gain unauthorized access to networks and machines. No authentication is required for an attacker to leverage these vulnerabilities to compromise a network or machine.
