Xion Audio Player versions 1.0.126 and prior are vulnerable to a Unicode-based stack buffer overflow triggered by opening a specially crafted .m3u playlist file. The file contains an overly long string that overwrites the Structured Exception Handler (SEH) chain, allowing an attacker to hijack execution flow and run arbitrary code.
CVE-2010-20042
This high-severity CVE scores 8.4 under NVD CVSS v3. EPSS exploit probability: 9.7%, top 7% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
