## What is CVE-2022-2867?

CVE-2022-2867 is a medium-severity vulnerability in Debian Debian Linux, published on 17 Aug 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

libtiff's tiffcrop utility has a uint32_t underflow that can lead to out of bounds read and write. An attacker who supplies a crafted file to tiffcrop (likely via tricking a user to run tiffcrop on it with certain parameters) could cause a crash or in some cases, further exploitation.

Weakness: CWE-787 (Out-of-bounds Write), CWE-125 (Out-of-bounds Read), CWE-191 (Integer Underflow (Wrap or Wraparound))

Check this codebase for CVE-2022-2867 and fix it if it is affected.

What it is: CVE-2022-2867 is a medium-severity vulnerability in Debian Debian Linux, published on 17 Aug 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2022-2867 in the wild and no public exploit code.

Affected product: Debian Debian Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
