## What is CVE-2022-2869?

CVE-2022-2869 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 tool has a uint32_t underflow which leads to out of bounds read and write in the extractContigSamples8bits routine. An attacker who supplies a crafted file to tiffcrop could trigger this flaw, most likely by tricking a user into opening the crafted file with tiffcrop. Triggering this flaw could cause a crash or potentially further exploitation.

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

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2022-2869 and fix it if it is affected.

What it is: CVE-2022-2869 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-2022-2869 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.
