openSUSE Leap 15.0: 2018:1914-1 moderate: unzip Denial of Service

opensuse
Calendar Grey July 7, 2018
Dist Opensuse Esm H88
Minor revision for openSUSE tackling concerns in unzip linked to service denial and buffer overflow weaknesses.
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)

(bnc#910683)

This update was imported from the SUSE:SLE-15:Update update project.
