## What is CVE-2012-3455?

CVE-2012-3455 is a high-severity memory corruption vulnerability in n/a, published on 20 Aug 2012. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

Heap-based buffer overflow in the read function in filters/words/msword-odf/wv2/src/styles.cpp in the Microsoft import filter in KOffice 2.3.3 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted ODF style in an ODF document.  NOTE: this is the same vulnerability as CVE-2012-3456, but it was SPLIT by the CNA even though Calligra and KOffice share the same codebase.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)

Check this codebase for CVE-2012-3455 and fix it if it is affected.

What it is: CVE-2012-3455 is a high-severity memory corruption vulnerability in n/a, published on 20 Aug 2012. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2012-3455 in the wild and no public exploit code.

Affected product: n/a. 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.
