CVE-2025-48964 Integer overflow in iputils
Medium 6.5
Published
Updated
Check this codebase for CVE-2025-48964 and fix it if it is affected.
What it is: CVE-2025-48964 is a medium-severity vulnerability in iputils, published on 22 Jul 2025. 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-2025-48964 exists.
Affected product: iputils. 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-2025-48964?
CVE-2025-48964 is a medium-severity vulnerability in iputils, published on 22 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
ping in iputils before 20250602 allows a denial of service (application error in adaptive ping mode or incorrect data collection) via a crafted ICMP Echo Reply packet, because a zero timestamp can lead to large intermediate values that have an integer overflow when squared during statistics calculations. NOTE: this issue exists because of an incomplete fix for CVE-2025-47268 (that fix was only about timestamp calculations, and it did not account for a specific scenario where the original timestamp in the ICMP payload is zero).
Weakness: CWE-190
