CVE-2023-36054 – krb5: Denial of service through freeing uninitialized pointer
https://notcve.org/view.php?id=CVE-2023-36054
lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count. A vulnerability was found in the _xdr_kadm5_principal_ent_rec() function in lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (krb5). This issue occurs due to lack of validation in the relationship between n_key_data and the key_data array count, leading to the freeing of uninitialized pointers. • https://github.com/krb5/krb5/commit/ef08b09c9459551aabbe7924fb176f1583053cdd https://github.com/krb5/krb5/compare/krb5-1.20.1-final...krb5-1.20.2-final https://github.com/krb5/krb5/compare/krb5-1.21-final...krb5-1.21.1-final https://lists.debian.org/debian-lts-announce/2023/10/msg00031.html https://security.netapp.com/advisory/ntap-20230908-0004 https://web.mit.edu/kerberos/www/advisories https://access.redhat.com/security/cve/CVE-2023-36054 https://bugzilla.redhat.com • CWE-824: Access of Uninitialized Pointer •

CVE-2023-4004 – Kernel: netfilter: use-after-free due to improper element removal in nft_pipapo_remove()
https://notcve.org/view.php?id=CVE-2023-4004
A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system. Se encontró una falla de use-after-free en el netfilter del kernel de Linux en la forma en que un usuario activa la función nft_pipapo_remove con el elemento, sin un NFT_SET_EXT_KEY_END.
