CVE-2012-3057: Heap-based buffer overflow in the Cisco WebEx Recording Format (WRF) player T27 L through SP11 EP26, T27 LB...

Security readout for executives and security teams

CVE-2012-3057 is a Cisco WebEx WRF Player flaw where a malicious recording file could trigger memory corruption and run code on the user's system. Business risk is mainly endpoint compromise through unsafe handling of WebEx recording files, especially on systems with old WebEx Player versions. Exposure is limited to environments where affected Cisco WebEx WRF Player versions are installed or available to open WRF files. The bundle lists specific vulnerable T27 and T28 release ranges but does not provide asset prevalence or deployment scope. Treat as a targeted endpoint-compromise risk, not an internet-facing infrastructure emergency. Prioritize remediation where legacy WebEx recording playback remains installed, especially for users likely to receive external meeting recordings. Mitigation focus: Identify installed Cisco WebEx WRF Player versions across managed endpoints.; Review Cisco advisory cisco-sa-20120627-webex for fixed or supported versions.; Upgrade or remove affected WebEx Player builds where no business need remains..
