Changelog

klibc (2.0.7-1ubuntu5.2) focal-security; urgency=medium

  * SECURITY UPDATE: improper pointer arithmetic
    - debian/patches/CVE-2016-9840.patch: remove offset pointer optimization
      in usr/klibc/zlib/inftrees.c.
    - CVE-2016-9840
  * SECURITY UPDATE: improper pointer arithmetic
    - debian/patches/CVE-2016-9841.patch: remove offset pointer optimization
      in usr/klibc/zlib/inffast.c.
    - CVE-2016-9841
  * SECURITY UPDATE: memory corruption during compression
    - debian/patches/CVE-2018-25032.patch: addresses a bug that can crash
      deflate on rare inputs when using Z_FIXED.
    - CVE-2018-25032
  * SECURITY UPDATE: heap-based buffer over-read
    - debian/patches/CVE-2022-37434-1.patch: adds an extra condition to check
      if state->head->extra_max is greater than len before copying, and moves
      the len assignment to be placed before the check in
      usr/klibc/zlib/inflate.c.
    - debian/patches/CVE-2022-37434-2.patch: in the previous patch, the
      placement of the len assignment was causing issues so it was moved
      within the conditional check.
    - CVE-2022-37434
