CVE-2014-9482
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 · uneditedUse-after-free vulnerability in dwarfdump in libdwarf 20130126 through 20140805 might allow remote attackers to cause a denial of service (program crash) via a crafted ELF file.
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 confidenceA use-after-free vulnerability exists in the dwarfdump utility of libdwarf versions 20130126 through 20140805. The vulnerability is triggered when processing a specially crafted ELF file, causing the program to access freed memory, resulting in a denial of service via program crash.

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.
-
Locate dwarfdump or libdwarf installationRun 'which dwarfdump' or search for libdwarf files using 'find /usr -name "*dwarf*" -type f 2>/dev/null'Affected if dwarfdump or libdwarf library files are found on the system
-
Determine installed libdwarf versionRun 'dwarfdump -V' or 'dwarfdump --version', or check the library version with 'ls -la' on the libdwarf shared library fileAffected if The version displayed matches the date-based format between 20130126 and 20140805 inclusive
-
Check libdwarf package versionIf installed via package manager, run 'dpkg -l | grep libdwarf' (Debian) or 'rpm -qa | grep -i libdwarf' (RHEL/CentOS)Affected if The package version falls within the affected date range 20130126 to 20140805
-
Verify dwarfdump processes ELF filesReview any scripts, automated tools, or workflows that invoke dwarfdump to process ELF/binary filesAffected if dwarfdump is used to analyze ELF files, particularly from untrusted sources
The system is affected if libdwarf or dwarfdump is installed with a version date between 20130126 and 20140805 inclusive, and dwarfdump is used to process ELF files.

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 dataUpdate libdwarf to a version after 20140805 that contains the fix, or apply vendor patches. Additionally, implement input validation and avoid processing untrusted ELF files with dwarfdump until the patch is applied.
