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 · unedited
Larry Wall's patch; patch in FreeBSD 10.2-RC1 before 10.2-RC1-p1, 10.2 before 10.2-BETA2-p2, and 10.1 before 10.1-RELEASE-p16; Bitrig; GNU patch before 2.2.5; and possibly other patch variants allow remote attackers to execute arbitrary shell commands via a crafted patch 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 · high confidence

Arbitrary command execution vulnerability in multiple patch implementations (GNU patch, FreeBSD patch, Bitrig) where a specially crafted patch file can inject and execute arbitrary shell commands when applied. The vulnerability stems from insufficient validation of patch file content allowing shell metacharacters to be interpreted by the underlying shell during patch application.

MitigationAvoid applying untrusted or unverified patch files. Update affected patch utilities to the fixed versions (GNU patch 2.2.5+, FreeBSD 10.1-RELEASE-p16, 10.2-BETA2-p2, or 10.2-RC1-p1). Consider running patch in isolated sandboxed environments as an additional safeguard.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check FreeBSD base system version
    Run `uname -a` or `freebsd-version` to identify the installed FreeBSD release version
    Affected if The version shows 10.0, 10.1, or 10.2
  2. Identify patch utility origin
    Run `which patch` and `patch --version` to determine if the system uses FreeBSD patch or GNU patch
    Affected if Running FreeBSD 10.0-10.2 with its native patch utility (not a separately installed GNU patch)
  3. Check GNU patch version if installed separately
    If GNU patch is installed via ports/packages, run `pkg info` or check the installed version against vulnerable ranges
    Affected if GNU patch versions prior to 2.2.5 are installed on the system

A system is affected if it runs FreeBSD 10.0, 10.1, or 10.2 and uses the native FreeBSD patch utility to apply untrusted or unverified patch files containing shell metacharacters.

Mitigation

Avoid applying untrusted or unverified patch files. Update affected patch utilities to the fixed versions (GNU patch 2.2.5+, FreeBSD 10.1-RELEASE-p16, 10.2-BETA2-p2, or 10.2-RC1-p1). Consider running patch in isolated sandboxed environments as an additional safeguard.
