CVE-2025-25724 is a medium-severity denial of service vulnerability in Libarchive Libarchive, published on 2 Mar 2025. It can only be exploited from the same machine or local network, with no action from the victim. ### Official description list_item_verbose in tar/util.c in libarchive through 3.7.7 does not check an strftime return value, which can lead to a denial of service or unspecified other impact via a crafted TAR archive that is read with a verbose value of 2. For example, the 100-byte buffer may not be sufficient for a custom locale. Weakness: CWE-252 (Unchecked Return Value) ## Which versions are affected by CVE-2025-25724?

What it is: CVE-2025-25724 is a medium-severity denial of service vulnerability in Libarchive Libarchive, published on 2 Mar 2025. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2025-25724 in the wild and no public exploit code. Affected product: Libarchive Libarchive. 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.
