3. Description:

 

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 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)

 

Red Hat would like to thank Insomnia Security for reporting CVE-2016-5418.
