Digital media delivery firm RealNetworks Inc. late Thursday shipped a major security update for its RealPlayer software to patch a pair of remote code execution vulnerabilities. The security holes, which were reported to RealNetworks more than four months ago, could be exploited by malicious hackers to take complete control over a vulnerable machine. According to eEye Digital Security, the company that discovered the bugs, the most serious flaw exists in the first data packet contained in a Real Media file.
