Details

It was discovered that the GNU C Library incorrectly handled the
GLIBC_TUNABLES environment variable. An attacker could possibly use this
issue to perform a privilege escalation attack. (CVE-2023-4911)

It was discovered that the GNU C Library incorrectly handled certain DNS
responses when the system was configured in no-aaaa mode. A remote attacker
could possibly use this issue to cause the GNU C Library to crash,
resulting in a denial of service. This issue only affected Ubuntu 23.04.
(CVE-2023-4527)
