CVE-2014-9636

unzip 6.0 allows remote attackers to cause a 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.

These are all security issues fixed in the unzip-6.00-39.1 package on the GA media of openSUSE Tumbleweed.

unzip was updated to fix one security issue.

This security issue was fixed:

• Out-of-bounds read/write in test_compr_eb() in extract.c (CVE-2014-9636).

This update fixes the following security issues:

* CVE-2014-8139: input sanitization errors (bnc#909214)
* CVE-2014-9636: out-of-bounds read/write in test_compr_eb()
  (bnc#914442)

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 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).

unzip 6.0 allows remote attackers to cause a 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.

Michal Zalewski discovered that unzip incorrectly handled certain malformed zip archives. If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly execute arbitrary code.
