"This update for unzip fixes the following issues :

  - CVE-2014-9636: Prevent denial of service (out-of-bounds
    read or write and crash) via an extra field with an
    uncompressed size smaller than the compressed field size
    in a zip archive that advertises STORED method
    compression (bsc#914442)

  - CVE-2018-1000035: Prevent heap-based buffer overflow in
    the processing of password-protected archives that
    allowed an attacker to perform a denial of service or to
    possibly achieve code execution (bsc#1080074)

The update package also includes non-security fixes. See advisory for
details.

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.");
