CVE-2005-2922

CWE-119Published: December 31, 2005· Updated: Jun 16, 2026

9.3

CVSS v3.1

Official Description

Heap-based buffer overflow in the embedded player in multiple RealNetworks products and versions including RealPlayer 10.x, RealOne Player, and Helix Player allows remote malicious servers to cause a denial of service (crash) and possibly execute arbitrary code via a chunked Transfer-Encoding HTTP response in which either (1) the chunk header length is specified as -1, (2) the chunk header with a length that is less than the actual amount of sent data, or (3) a missing chunk header.

Technical Analysis

CVE-2005-2922 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
