RealPlayer is a multimedia player capable of handling multiple multimedia file formats.
Dyon Balding of Secunia Research reported an unspecified heap-based buffer overflow in the Shockwave Flash (SWF) frame handling.
By enticing a user to open a specially crafted SWF (Shockwave Flash) file, a remote attacker could be able to execute arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All RealPlayer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/realplayer-11.0.0.4028-r1"
