MJM QuickPlayer (also known as MJM Player) version 2010 contains a stack-based buffer overflow vulnerability triggered by opening a malicious .s3m music file. The flaw occurs due to improper bounds checking in the file parser, allowing an attacker to overwrite memory and execute arbitrary code. Exploitation is achieved via a crafted payload that bypasses DEP and ASLR protections using ROP techniques, and requires user interaction to open the file.

MITRE Common Weakness Enumeration — the root-cause categories this CVE belongs to.

Data Freshness Timeline

(refreshed 7× in last 7d / 18× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 79 of 113 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 21 repeat rows among the latest 100 are merged into the row they repeat. The 34 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
