The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters.", "A flaw was found in the Tar package. When attempting to read files with old V7 tar format with a specially crafted checksum, an invalid memory read may occur. An attacker could possibly use this issue to expose sensitive information or cause a crash." ],
