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.
