CVE-2016-9266
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedlistmp3.c in libming 0.4.7 allows remote attackers to unspecified impact via a crafted mp3 file, which triggers an invalid left shift.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe vulnerability exists in listmp3.c of libming 0.4.7 where parsing a crafted mp3 file triggers an invalid left shift operation. This is likely due to missing bounds checking on integer values before shift operations, potentially causing integer overflow and leading to undefined behavior or memory corruption.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if libming is installedRun 'pkg-config --modversion libming' or check your system's package manager for libming packages (dpkg -l | grep libming, rpm -qa | grep libming, etc.)Affected if The installed version is exactly 0.4.7
-
Locate libming library filesSearch for libming shared objects: 'find /usr -name "libming*.so*" 2>/dev/null' or check /usr/lib or /usr/local/lib directoriesAffected if Library files from version 0.4.7 are present on the system
-
Identify binaries using listmp3 functionalityCheck for utilities that parse mp3 files via libming: 'which listmp3' or 'find /usr -name "*mp3*" -type f -executable 2>/dev/null' and review any mp3-related tools in libming's bin directoryAffected if listmp3 or mp3 parsing utilities from libming are present and used
-
Audit applications linking to libmingRun 'ldd /path/to/application | grep ming' on suspect applications, or use 'strings' on application binaries to search for libming function calls related to mp3 parsingAffected if Applications link against libming and process mp3 files using its mp3 parsing functions
A system is affected if libming version 0.4.7 is installed and any application or tool uses it to parse mp3 files, as the vulnerability lies in the listmp3.c mp3 parsing component.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade libming to a patched version; implement strict input validation on mp3 files before processing to reject malformed files.
