Security patches issued for RealPlayers

RealNetwork's patches address vulnerabilities in the software that would allow an attacker to run arbitrary or malicious code on a person's computer when a malicious WAV or SMIL file is processed.

Secunia, a security information company, rated the vulnerabilities as "critical."

RealNetworks released updates on Tuesday for flaws in the Mac RealPlayer 10 and these Windows players: RealPlayer 10.5, RealPlayer 10, RealPlayer Enterprise and certain versions of RealOne Player v2.

Upgrades are required for Windows players RealOne Player v1, RealPlayer 8 and certain versions of RealOne Player v2. Upgrades are also needed for the Mac RealOne Player, Linux RealPlayer 10, and the Helix Player for Linux.

Another flaw was discovered in the players in October. That vulnerability could have allowed an attacker to create fake movie files that would run a program on victims' computers.
