In Real Player through 20.1.0.312, attackers can execute arbitrary code by placing a UNC share pathname (for a DLL file) in a RAM file.

In Real Player 20.0.8.310, there is a DCP:// URI Remote Arbitrary Code Execution Vulnerability. This is an internal URL Protocol used by Real Player to reference a file that contains an URL. It is possible to inject script code to arbitrary domains. It is also possible to reference arbitrary local files.

In Real Player 20.0.7.309 and 20.0.8.310, external::Import() allows download of arbitrary file types and Directory Traversal, leading to Remote Code Execution. This occurs because it is possible to plant executables in the startup folder (DLL planting could also occur).

In Real Player 20.0.8.310, the G2 Control allows injection of unsafe javascript: URIs in local HTTP error pages (displayed by Internet Explorer core). This leads to arbitrary code execution.

RealOne Player 2.0 Build 6.0.11.872 allows remote attackers to cause a denial of service (array out-of-bounds access and application crash) via a crafted .aiff file.

RealPlayer 16.0.2.32 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted mp4 file.

Improper handling of a repeating VRAT chunk in qcpfformat.dll allows attackers to cause a Null pointer dereference and crash in RealNetworks RealPlayer 18.1.5.705 through a crafted .QCP media file.

RealNetworks GameHouse RealArcade Installer (aka ActiveMARK Game Installer) 2.6.0.481 and 3.0.7 uses weak permissions (Create Files/Write Data) for the GameHouse Games directory tree, which allows local users to gain privileges via a Trojan horse DLL in an individual game's directory, as demonstrated by DDRAW.DLL in the Zuma Deluxe directory.

The RACInstaller.StateCtrl.1 ActiveX control in InstallerDlg.dll in RealNetworks GameHouse RealArcade Installer 2.6.0.481 performs unexpected type conversions for invalid parameter types, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via crafted arguments to the (1) AddTag, (2) Ping, (3) QueuePause, (4) QueueRemove, (5) QueueTop, (6) RemoveTag, (7) TagRemoved, or (8) message method.

Multiple buffer overflows in RealNetworks RealPlayer before 17.0.10.8 allow remote attackers to execute arbitrary code via a malformed (1) elst or (2) stsz atom in an MP4 file.
