Ubuntu Security Notice 3225-1 - It was discovered that libarchive incorrectly handled hardlink entries when extracting archives. A remote attacker could possibly use this issue to overwrite arbitrary files. Christian Wressnegger, Alwin Maier, and Fabian Yamaguchi discovered that libarchive incorrectly handled filename lengths when writing ISO9660 archives. A remote attacker could use this issue to cause libarchive to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Various other issues were also addressed.

Red Hat Security Advisory 2016-1850-01
Posted Sep 12, 2016

Red Hat Security Advisory 2016-1850-01 - 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: 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.

Red Hat Security Advisory 2016-1853-01 - OpenShift Enterprise by Red Hat is the company's cloud computing Platform- as-a-Service solution designed for on-premise or private cloud deployments. Security Fix: When processing an archive file that contains an archive entry with type 1 but also having a non-zero data size a file overwrite can occur. This would allow an attacker that can pass data to an application that uses libarchive to unpack it to overwrite arbitrary files with arbitrary data.
