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 write flaws were found in libarchive. Specially
crafted ZIP, 7ZIP, or RAR files could cause a heap overflow, potentially
allowing code execution in the context of the application using
libarchive. (CVE-2016-1541, CVE-2016-4300, CVE-2016-4302)

* Multiple out-of-bounds read flaws were found in libarchive. Specially
crafted LZA/LZH, AR, MTREE, ZIP, TAR, or RAR 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-2015-8919, CVE-2015-8920, CVE-2015-8921, CVE-2015-8923,
CVE-2015-8924, CVE-2015-8925, CVE-2015-8926, CVE-2015-8928, CVE-2015-8934)

* Multiple NULL pointer dereference flaws were found in libarchive.
Specially crafted RAR, CAB, or 7ZIP files could cause an application using
libarchive to crash. (CVE-2015-8916, CVE-2015-8917, CVE-2015-8922)

* Multiple infinite loop / resource exhaustion flaws were found in
libarchive. Specially crafted GZIP or ISO files could cause the
application to consume an excessive amount of resources, eventually
leading to a crash on memory exhaustion. (CVE-2016-7166, CVE-2015-8930)

* 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)

* An integer overflow flaw, leading to a buffer overflow, was found in
libarchive's construction of ISO9660 volumes. Attempting to create an
ISO9660 volume with 2 GB or 4 GB file names could cause the application to
attempt to allocate 20 GB of memory. If this were to succeed, it could
lead to an out of bounds write on the heap and potential code execution.
(CVE-2016-6250)

* Multiple instances of undefined behavior due to arithmetic overflow were
found in libarchive. Specially crafted MTREE archives, Compress streams,
or ISO9660 volumes could potentially cause the application to fail to read
the archive, or to crash. (CVE-2015-8931, CVE-2015-8932, CVE-2016-5844)
