Description Agostino Sarubbo gentoo-dev 2015-04-29 07:31:06 UTC 
From ${URL} :

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.
