RealPlayer is prone to an overflow condition. The drv1.dll module fails to properly sanitize user-supplied input resulting in an integer overflow. With a specially crafted .rm file, a context-dependent attacker can potentially execute arbitrary code.
Upgrade RealPlayer to version 14.0.0 or SP 1.1.5 or higher for Windows, 11.0.2.2315 or higher for Linux, and RealPlayer Enterprise to version 2.1.3 or higher, as they have been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
