[Bug 1729414] Re: zlib package in Ubuntu 14.04 LTS (Trusty) has not received patches for critical/high CVE-2016-9840, CVE-2016-9841, CVE-2016-9842, CVE-2016-9843

[Marc Deslauriers]

We have rated these vulnerabilities as being "low" priority as the
undefined behaviour doesn't affect binaries built with gcc.

We will include them in a zlib security update if more important issues
need to be addressed.

Title:
  zlib package in Ubuntu 14.04 LTS (Trusty) has not received patches for
  critical/high CVE-2016-9840, CVE-2016-9841, CVE-2016-9842,
  CVE-2016-9843

Status in zlib package in Ubuntu:
  Confirmed

Bug description:
  The current package available to 14.04/trusty is 1:1.2.8.dfsg-1ubuntu1
  which does not have the upstream fixes for the following CVEs:

  * CVE-2016-9840 (high) (https://nvd.nist.gov/vuln/detail/CVE-2016-9840)
  * CVE-2016-9841 (critical) (https://nvd.nist.gov/vuln/detail/CVE-2016-9841)
  * CVE-2016-9842 (high) (https://nvd.nist.gov/vuln/detail/CVE-2016-9842)
  * CVE-2016-9843 (critical) (https://nvd.nist.gov/vuln/detail/CVE-2016-9843)

  Being that they are being categorized as such by NIST, it would be
  very nice to get these fixes backported to Trusty or the most recent
  version of zlib made available to Trusty.

  Thanks!
