decompress: Decompress: File disclosure and corruption via arbitrary hardlink creation

A flaw was found in decompress. An attacker can craft a malicious archive that, when extracted, allows for arbitrary hardlink creation. This vulnerability occurs because the x.linkname field from hardlink entries in the archive is processed without proper validation, enabling an attacker to creat...
