"This update for libarchive fixes several issues. These security issues
were fixed :

  - CVE-2016-8687: Buffer overflow when printing a filename
    (bsc#1005070).

  - CVE-2016-8689: Heap overflow when reading corrupted 7Zip
    files (bsc#1005072).

  - CVE-2016-8688: Use after free because of incorrect
    calculation in next_line (bsc#1005076).

  - CVE-2016-5844: Integer overflow in the ISO parser in
    libarchive allowed remote attackers to cause a denial of
    service (application crash) via a crafted ISO file
    (bsc#986566).

  - CVE-2016-6250: Integer overflow in the ISO9660 writer in
    libarchive allowed remote attackers to cause a denial of
    service (application crash) or execute arbitrary code
    via vectors related to verifying filename lengths when
    writing an ISO9660 archive, which trigger a buffer
    overflow (bsc#989980).

  - CVE-2016-5418: The sandboxing code in libarchive
    mishandled hardlink archive entries of non-zero data
    size, which might allowed remote attackers to write to
    arbitrary files via a crafted archive file (bsc#998677).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
