CVE-2015-5229 Denial of service in n/a
High 7.5
Published
Updated
Check this codebase for CVE-2015-5229 and fix it if it is affected.
What it is: CVE-2015-5229 is a high-severity denial of service vulnerability in Redhat Enterprise Linux, published on 8 Apr 2016. 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-2015-5229 in the wild and no public exploit code.
Affected product: Redhat Enterprise Linux. 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-2015-5229?
CVE-2015-5229 is a high-severity denial of service vulnerability in Redhat Enterprise Linux, published on 8 Apr 2016. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The calloc function in the glibc package in Red Hat Enterprise Linux (RHEL) 6.7 and 7.2 does not properly initialize memory areas, which might allow context-dependent attackers to cause a denial of service (hang or crash) via unspecified vectors.
