Background ========== GNU cpio copies files into or out of a cpio or tar archive. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/cpio < 2.11-r3 >= 2.11-r3 Description =========== Two vulnerabilities have been discovered in GNU cpio: * The list_file function in GNU cpio contains a heap-based buffer overflow vulnerability (CVE-2014-9112) * A directory traversal vulnerability has been found in GNU cpio (CVE-2015-1197) Impact ====== A remote attacker may be able to entice a user to open a specially crafted archive using GNU cpio, possibly resulting in execution of arbitrary code, a Denial of Service condition, or overwriting arbitrary files.
