CVE-2015-7696

Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.

These are all security issues fixed in the unzip-6.00-31.1 package on the GA media of openSUSE Tumbleweed.

This update for unzip fixes the following 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)

Info-ZIP UnZip 6.0 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly execute arbitrary code via a crafted password-protected ZIP archive, possibly related to an Extra-Field size value.

Gustavo Grieco discovered that unzip incorrectly handled certain password protected archives. If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly execute arbitrary code. (CVE-2015-7696)

Gustavo Grieco discovered that unzip incorrectly handled certain malformed archives. If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly cause unzip to hang, resulting in a denial of service. (CVE-2015-7697)
