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) (bnc#910683)
