   An update that solves two vulnerabilities and has one
   errata is now available.

Description:

   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)

   This non-security issue was fixed:

   +- Allow processing of Windows zip64 archives (Windows archivers set
    total_disks field to 0 but per standard, valid values are 1 and higher)
