RealNetworks RealPlayer and HelixPlayer SmilTimeValue::parseWallClockValue() buffer overflow
| realplayer-smiltime-wallclockvalue-bo (35088) |  High Risk |
Description:
RealNetworks RealPlayer and HelixPlayer are vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the SmilTimeValue::parseWallClockValue() function. By persuading a victim to open a specially-crafted SMIL file containing an overly long time string, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
