[Rodrigo Figueiredo Zaiden]

zlib (1:1.2.11.dfsg-2ubuntu1.5) focal-security; urgency=medium

  * SECURITY UPDATE: heap-based buffer over-read (LP: #1988548)
    - debian/patches/CVE-2022-37434-1.patch: in inflate.c, add an extra
      condition to check if state->head->extra_max is greater than len
      before copying, and move the len assignment to be placed before the
      check.
    - debian/patches/CVE-2022-37434-2.patch: in the previous patch, in
      inflate.c, the place of the len assignment was causing issues so it
      was moved to be placed within the check.
    - CVE-2022-37434

zlib (1:1.2.11.dfsg-2ubuntu1.4) focal; urgency=medium

  * d/p/410-lp1961427.patch ported from zlib #410, fixing
    compressBound() with hw acceleration. LP: #1961427
    Thanks to Ilya Leoshkevich <iii at linux.ibm.com>.
    In addition a patch is needed in htslib.
