USN-2788-1 and USN-2788-2 unzip vulnerability

Medium

Vendor

unzip

Versions Affected

  • Ubuntu 14.04

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)

The Cloud Foundry project released a BOSH stemcell version 3130 that has the patched version of the Linux kernel. A new Cloud Foundry rootfs was also released, cflinuxfs2 v.1.17.0, that has the patches.

Affected Products and Versions

Severity is medium unless otherwise noted.

  • All versions of Cloud Foundry BOSH stemcells prior to 3130 have versions of the kernel vulnerable to USN-2806-1.
  • All versions of Cloud Foundry cflinuxfs2 prior to v.1.17.0.

Mitigation

Users of affected versions should apply the following mitigation:

  • The Cloud Foundry project recommends that Cloud Foundry deployments run with BOSH stemcells 3130 or later versions and cflinuxfs2 v.1.17.0 or later versions.
