## What is CVE-2002-1146?

CVE-2002-1146 is a medium-severity memory corruption vulnerability in Gnu Glibc, published on 1 Sep 2004. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash).

## Which versions are affected by CVE-2002-1146?

It affects 1 product.


Products: Gnu Glibc.

## How do I fix CVE-2002-1146?

Upgrade to a fixed version.

## Is CVE-2002-1146 being exploited?

There is no known exploitation of CVE-2002-1146 in the wild and no public exploit code.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2002-1146 and fix it if it is affected.

What it is: CVE-2002-1146 is a medium-severity memory corruption vulnerability in Gnu Glibc, published on 1 Sep 2004. 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-2002-1146 in the wild and no public exploit code.

Affected product: Gnu Glibc. 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.
