Description Martin Prpič 2015-04-29 07:10:55 UTC

An out-of-bounds read flaw was found in the way libarchive processed certain CPIO archives. An attacker could create a specially crafted CPIO archive that, when processed by an application using the libarchive library, would cause that application to crash.
