What is CVE-2015-8930?

The bsdtar utility in libarchive versions prior to 3.2.0 is susceptible to a denial-of-service vulnerability, enabling remote attackers to induce an infinite loop. This can occur when processing a specially crafted ISO file that contains a directory which recursively references itself, leading to potential resource exhaustion and service disruption. It is crucial for users relying on libarchive to ensure their systems are updated to the latest version to mitigate this risk.
