CVE-2009-2412 Integer overflow in n/a
Critical 10.0
Published
Updated
Check this codebase for CVE-2009-2412 and fix it if it is affected.
What it is: CVE-2009-2412 is a critical vulnerability in n/a, published on 6 Aug 2009. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2009-2412 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.

What is CVE-2009-2412?
CVE-2009-2412 is a critical vulnerability in n/a, published on 6 Aug 2009. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Multiple integer overflows in the Apache Portable Runtime (APR) library and the Apache Portable Utility library (aka APR-util) 0.9.x and 1.3.x allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger crafted calls to the (1) allocator_alloc or (2) apr_palloc function in memory/unix/apr_pools.c in APR; or crafted calls to the (3) apr_rmm_malloc, (4) apr_rmm_calloc, or (5) apr_rmm_realloc function in misc/apr_rmm.c in APR-util; leading to buffer overflows. NOTE: some of these details are obtained from third party information.
Weakness: CWE-189
