VUL-0: CVE-2023-4813: glibc: potential use-after-free in gaih_inet()
Last modified: 2024-05-13 14:38:50 UTC
CVE-2023-4813 In an uncommon situation, the gaih_inet function in glibc may use memory that has already been freed, resulting in an application crash. This issue is only exploitable when the getaddrinfo function is called and the hosts database in /etc/nsswitch.conf is configured with SUCCESS=continue or SUCCESS=merge. This flaw affects glibc versions prior to 2.36.
