RealNetworks RealPlayer 10.1.0.3114 and earlier, and Helix Player 1.0.6.778 on Fedora Core 6 (FC6) and possibly other platforms, allow user-assisted remote attackers to cause a denial of service (application crash) via a malformed .au file that triggers a divide-by-zero error.

Stack-based buffer overflow in the SmilTimeValue::parseWallClockValue function in smlprstime.cpp in RealNetworks RealPlayer 10, 10.1, and possibly 10.5, RealOne Player, RealPlayer Enterprise, and Helix Player 10.5-GOLD and 10.0.5 through 10.0.8, allows remote attackers to execute arbitrary code via an SMIL (SMIL2) file with a long wallclock value.
