What is CVE-2017-12378?

A vulnerability in ClamAV AntiVirus software versions up to 0.99.2 can be exploited by unauthenticated, remote entities to induce a denial of service condition. This issue arises due to inadequate validation of .tar archive file inputs. When ClamAV processes a malicious .tar file, it may trigger a checksum buffer over-read, resulting in service disruption for the affected device. Immediate updates to patched versions are recommended to mitigate potential risks.
