RealPlayer before 15.0.0 allows remote code execution via a malformed AAC file.

Vulnerability

RealNetworks RealPlayer versions prior to 15.0.0 contain a vulnerability in the parsing of AAC audio files. A malformed AAC file can trigger memory corruption, allowing an attacker to execute arbitrary code. No special configuration is required beyond opening the malicious file [1].

Exploitation

An attacker can deliver a crafted AAC file through a webpage, email attachment, or other means. User interaction is required, such as clicking to play the file. No authentication or prior access is needed [1].

Impact

Successful exploitation results in arbitrary code execution in the context of the RealPlayer process. This can lead to full compromise of the affected system, including disclosure, modification, or destruction of data, and potential further attacks [1].

Mitigation

The vulnerability is fixed in RealPlayer 15.0.0, released on or around November 18, 2011 [1]. Users should upgrade to this version or later. No workarounds are documented, and this CVE is not listed in the CISA Known Exploited Vulnerabilities catalog.
