An ActiveX control in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.4, and RealPlayer Enterprise 2.1.2 does not properly initialize an unspecified object component during parsing of a CDDA URI, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized pointer dereference and application crash) via a long URI.

Heap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1, RealPlayer SP 1.0 through 1.1.4, and RealPlayer Enterprise 2.1.2 allows remote attackers to have an unspecified impact via a crafted QCP file.

Unspecified vulnerability in an ActiveX control in the Internet Explorer (IE) plugin in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1.4 on Windows has unknown impact and attack vectors related to "multiple browser windows."

Multiple integer overflows in the ParseKnownType function in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1.4 on Windows allow remote attackers to execute arbitrary code via crafted (1) HX_FLV_META_AMF_TYPE_MIXEDARRAY or (2) HX_FLV_META_AMF_TYPE_ARRAY data in an FLV file.

Heap-based buffer overflow in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1.4 on Windows allows remote attackers to execute arbitrary code via large size values in QCP audio content.

RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1.4 on Windows do not properly handle dimensions during YUV420 transformations, which might allow remote attackers to execute arbitrary code via crafted MP4 content.

Integer overflow in RealNetworks RealPlayer 11.0 through 11.1 and RealPlayer SP 1.0 through 1.1.4 on Windows might allow remote attackers to execute arbitrary code via a crafted QCP file that triggers a heap-based buffer overflow.
