-+Security related changes: -+ -+ 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

We can still give it back if it can be merged -with the following unused chunk.
