Description:

This update for unzip fixes the following security issues:

– CVE-2014-9913: Specially crafted zip files could trigger invalid memory
writes possibly resulting in DoS or corruption (bsc#1013993)
– CVE-2015-7696: Specially crafted zip files with password protection
could trigger a crash and lead to denial of service (bsc#950110)
– CVE-2015-7697: Specially crafted zip files could trigger an endless loop
and lead to denial of service (bsc#950111)
– CVE-2016-9844: Specially crafted zip files could trigger invalid memory
writes possibly resulting in DoS or corruption (bsc#1013992)
– 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).
– 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).

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)
