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 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.
