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.
