[Launchpad Bug Tracker]

This bug was fixed in the package glibc - 2.35-0ubuntu3.6

---------------
glibc (2.35-0ubuntu3.6) jammy-security; urgency=medium

  * SECURITY REGRESSION: incorrect processing of address family with nscd
    (LP: #2047155)
    - debian/patches/lp2047155/lp2047155-refactor-bits-for-readability.patch:
      split out line processing for 'label', 'precedence' and 'scopev4' into
      separate functions (gaiconf_inet).
    - debian/patches/lp2047155/lp2047155-avoid-if-to-else-jump.patch: clean up
      another antipattern where code flows from an if condition to its else
      counterpart with a goto (gai_init).
    - debian/patches/lp2047155/lp2047155-refactor-code-for-readability.patch:
      refactor the code and make it easier to follow by removing the confusing
      close_retry goto jump (getaddrinfo).
    - debian/patches/lp2047155/
      lp2047155-get-nscd-addresses-fix-subscript-typos.patch: fix the
      subscript on air->family, which was accidentally set to 'count' when it
      should have remained as 'i' (get_nscd_addresses).
    - CVE-2023-4806
