Real Networks RealPlayer 'RA5' Files (CVE-2010-4383) Heap Overflow Vulnerability

Real Networks RealPlayer is prone to a heap overflow vulnerability because the software fails to perform adequate boundary-checks on user-supplied data.

Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the vulnerable application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects Windows RealPlayer SP 1.1.4 and prior, RealPlayer Enterprise 2.1.2 and prior, Mac RealPlayer 11.1 and prior, Linux RealPlayer 11.0.2.1744 and prior.

NOTE: This issue was previously discussed in BID 45327 (Real Networks RealPlayer Multiple Remote Vulnerabilities) but has been given its own record to better document it.
