Zusammenfassung:	The remote host is missing an update for the 'libarchive'; package(s) announced via the referenced advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'libarchive' package(s) announced via the referenced advisory. Vulnerability Insight: The libarchive programming library can create and read several different streaming archive formats, including GNU tar, cpio and ISO 9660 CD-ROM images. Libarchive is used notably in the bsdtar utility, scripting language bindings such as python-libarchive, and several popular desktop file managers. Security Fix(es): * A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive. (CVE-2016-5418) * Multiple out-of-bounds read flaws were found in libarchive. Specially crafted AR or MTREE files could cause the application to read data out of bounds, potentially disclosing a small amount of application memory, or causing an application crash. (CVE-2015-8920, CVE-2015-8921) * A denial of service vulnerability was found in libarchive's handling of GZIP streams. A crafted GZIP file could cause libarchive to allocate an excessive amount of memory, eventually leading to a crash. (CVE-2016-7166) * A denial of service vulnerability was found in libarchive. A specially crafted CPIO archive containing a symbolic link to a large target path could cause memory allocation to fail, causing an application using libarchive that attempted to view or extract such archive to crash. (CVE-2016-4809) * Multiple instances of undefined behavior due to arithmetic overflow were found in libarchive. Specially crafted Compress streams or ISO9660 volumes could potentially cause the application to fail to read the archive, or to crash. (CVE-2015-8932, CVE-2016-5844) Red Hat would like to thank Insomnia Security for reporting CVE-2016-5418. Affected Software/OS: libarchive on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages.
