Title:
  Missing fix for CVE-2022-37434 in zlib1g in focal and jammy

Status in zlib package in Ubuntu:
  In Progress

Bug description:
  There is a crictical security issue with zlib tracked here [1]

  The newest version in bionic [2] already has a security patch for it
  but the one in the focal [3] (and jammy) does not. As can be seen from
  their respective changelogs in the right hand side panel.

  Since zlib is loaded by lots of software, e.g. the apache weg server,
  this could be a problem. It seems that focal, jammy and bionic use the
  same base zlib version (1.2.11), so maybe the patch there could be
  recycled?

  I was asked to create a bug here after asking it as question here [4].
  Thank you very much for your hard work!
