Synopsis
========<\/p>\n
A vulnerability has been discovered in cpio, which can lead to arbitrary
code execution.<\/p>\n
Background
==========<\/p>\n
cpio is a file archival tool which can also read and write tar files.<\/p>\n
Affected packages
=================<\/p>\n
Package Vulnerable Unaffected
————- ———— ————
app-arch\/cpio < 2.13-r1 >= 2.13-r1<\/p>\n
Description
===========<\/p>\n
Multiple vulnerabilities have been discovered in cpio. Please review the
CVE identifiers referenced below for details.<\/p>\n
Impact
======<\/p>\n
GNU cpio allows attackers to execute arbitrary code via a crafted
pattern file, because of a dstring.c ds_fgetstr 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.<\/p>\n
Workaround
==========<\/p>\n
There is no known workaround at this time.<\/p>\n
Resolution
==========<\/p>\n
All cpio users should upgrade to the latest version:<\/p>\n
# emerge –sync
# emerge –ask –oneshot –verbose “>=app-arch\/cpio-2.13-r1”<\/p>\n
