  • glibc: buffer overflow in ld.so leading to privilege escalation (CVE-2023-4911)

  • glibc: Stack read overflow in getaddrinfo in no-aaaa mode (CVE-2023-4527)

  • glibc: potential use-after-free in getaddrinfo() (CVE-2023-4806)

  • glibc: potential use-after-free in gaih_inet() (CVE-2023-4813)
