A vulnerability allows remote attackers to execute code on vulnerable installations of RealPlayer. User interaction is required in that a user must open a malicious .ra/.ram file or visit a malicious web site. The specific flaw exists during the parsing of files with improperly defined size field in the RA header. Specifying a large unsigned value data can trigger a heap corruption and further result in arbitrary code execution under the context of the logged in user. RealPlayer version 6.x is affected.
