GNU cpio through 2.13 allows attackers to execute arbitrary code via a crafted pattern file, because of a dstring.c dsfgetstr integer overflow that triggers an out-of-bounds heap write. NOTE: it is unclear whether there are common cases where the pattern file, associated with the -E option, is untrusted data.

cpio, as used in build 2007.05.10, 2010.07.28, and possibly other versions, allows remote attackers to overwrite arbitrary files via a symlink within an RPM package archive.

GNU cpio could allow a local authenticated attacker to gain elevated privileges on the system, caused by the failure to properly validate input files when generating TAR archives. An attacker could exploit this vulnerability to inject any tar content and compromise the system.
