[SECURITY] [DLA 617-1] libarchive security update

Package : libarchive
Version : 3.0.4-3+wheezy3
CVE ID : CVE-2015-8915 CVE-2016-7166
Debian Bug : 784213

Several security vulnerabilities have been discovered in libarchive,
a multi-format archive and compression library. An attacker could
take advantage of these flaws to cause an out of bounds read or a
denial of service against an application using the libarchive12
library using a carefully crafted input file.

CVE-2015-8915

Paris Zoumpouloglou of Project Zero labs discovered a flaw in
libarchive bsdtar. Using a crafted file bsdtar can perform an
out-of-bounds memory read which will lead to a SEGFAULT.

CVE-2016-7166

Alexander Cherepanov discovered a flaw in libarchive compression
handling. Using a crafted gzip file, one can get libarchive to
invoke an infinite chain of gzip compressors until all the memory
has been exhausted or another resource limit kicks in.

For Debian 7 "Wheezy", these problems have been fixed in version
3.0.4-3+wheezy3.

We recommend that you upgrade your libarchive packages.
