## What is CVE-2009-1227?

### Official description

NOTE: this issue has been disputed by the vendor.  Buffer overflow in the PKI Web Service in Check Point Firewall-1 PKI Web Service allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long (1) Authorization or (2) Referer HTTP header to TCP port 18624.  NOTE: the vendor has disputed this issue, stating "Check Point Security Alert Team has analyzed this report. We've tried to reproduce the attack on all VPN-1 versions from NG FP2 and above with and without HFAs. The issue was not reproduced. We have conducted a thorough analysis of the relevant code and verified that we are secure against this attack. We consider this attack to pose no risk to Check Point customers."  In addition, the original researcher, whose reliability is unknown as of 20090407, also states that the issue "was discovered during a pen-test where the client would not allow further analysis.

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

What it is: CVE-2009-1227 is a critical memory corruption vulnerability in n/a, published on 2 Apr 2009. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2009-1227 exists.

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.
