package/{glibc, localedef}: security bump to version glibc-2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701

Fixes the following security issues:

  CVE-2023-4527: If the system is configured in no-aaaa mode via
  /etc/resolv.conf, getaddrinfo is called for the AF_UNSPEC address
  family, and a DNS response is received over TCP that is larger than
  2048 bytes, getaddrinfo may potentially disclose stack contents via
  the returned address data, or crash.

  CVE-2023-4806: When an NSS plugin only implements the
  _gethostbyname2_r and _getcanonname_r callbacks, getaddrinfo could use
  memory that was freed during buffer resizing, potentially causing a
  crash or read or write to arbitrary memory.

  CVE-2023-5156: The fix for CVE-2023-4806 introduced a memory leak when
  an application calls getaddrinfo for AF_INET6 with AI_CANONNAME,
  AI_ALL and AI_V4MAPPED flags set.

  CVE-2023-4911: If a tunable of the form NAME=NAME=VAL is passed in the
  environment of a setuid program and NAME is valid, it may result in a
  buffer overflow, which could be exploited to achieve escalated
  privileges.  This flaw was introduced in glibc 2.34.
