Description
The foreach function in ext/ccsv.c in Ccsv 1.1.0 allows remote attackers to cause a denial of service (double free and application crash) or possibly have unspecified other impact via a crafted file. NOTE: This has been disputed and it is argued that this is not present in version 1.1.0.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ccsv, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of ccsv for CVE-2017-15364. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
