## What is CVE-2006-2898?

CVE-2006-2898 is a high-severity memory corruption vulnerability in Digium Asterisk, published on 7 Jun 2006. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The IAX2 channel driver (chan_iax2) for Asterisk 1.2.x before 1.2.9 and 1.0.x before 1.0.11 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via truncated IAX 2 (IAX2) video frames, which bypasses a length check and leads to a buffer overflow involving negative length check.  NOTE: the vendor advisory claims that only a DoS is possible, but the original researcher is reliable.

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

Check this codebase for CVE-2006-2898 and fix it if it is affected.

What it is: CVE-2006-2898 is a high-severity memory corruption vulnerability in Digium Asterisk, published on 7 Jun 2006. 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-2006-2898 in the wild and no public exploit code.

Affected product: Digium Asterisk. 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.
