406636fe-055d-11e5-aab1-d050996490d0 | krb5 -- requires_preauth bypass in PKINIT-enabled KDC
MIT reports:
In MIT krb5 1.12 and later, when the KDC is configured
with PKINIT support, an unauthenticated remote attacker
can bypass the requires_preauth flag on a client principal
and obtain a ciphertext encrypted in the principal's
long-term key. This ciphertext could be used to conduct
an off-line dictionary attack against the user's password.

3f3837cc-48fb-4414-aa46-5b1c23c9feae | krb5 -- Multiple vulnerabilities
MIT reports:
CVE-2017-11368:
In MIT krb5 1.7 and later, an authenticated attacker can cause an
assertion failure in krb5kdc by sending an invalid S4U2Self or
S4U2Proxy request.
CVE-2017-11462:
RFC 2744 permits a GSS-API implementation to delete an existing
security context on a second or subsequent call to gss_init_sec_context()
or gss_accept_sec_context() if the call results in an error.
This API behavior has been found to be dangerous, leading to the
possibility of memory errors in some callers. For safety, GSS-API
implementations should instead preserve existing security contexts
on error until the caller deletes them.
All versions of MIT krb5 prior to this change may delete acceptor
contexts on error. Versions 1.13.4 through 1.13.7, 1.14.1 through
1.14.5, and 1.15 through 1.15.1 may also delete initiator contexts
on error.

3a888a1e-b321-11e4-83b2-206a8a720317 | krb5 -- Vulnerabilities in kadmind, libgssrpc, gss_process_context_token VU#540092
The MIT Kerberos team reports:
CVE-2014-5353: The krb5_ldap_get_password_policy_from_dn
function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in
MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP,
allows remote authenticated users to cause a denial of service
(daemon crash) via a successful LDAP query with no results, as
demonstrated by using an incorrect object type for a password
policy.
CVE-2014-5354: plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in
MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when
the KDC uses LDAP, allows remote authenticated users to cause a
denial of service (NULL pointer dereference and daemon crash) by
creating a database entry for a keyless principal, as
demonstrated by a kadmin "add_principal -nokey" or "purgekeys
-all" command.

MITKRB5-SA-2022-001 Vulnerabilities in PAC parsing:
Due to an integer overflow vulnerabilities in PAC parsing
An authenticated attacker may be able to cause a KDC or kadmind
process to crash by reading beyond the bounds of allocated memory,
creating a denial of service.
On 32-bit platforms an authenticated attacker may be able to
cause heap corruption resulting in an RCE.

a6986f0f-3ac0-11ee-9a88-206a8a720317 | krb5 -- Double-free in KDC TGS processing
SO-AND-SO reports:
When issuing a ticket for a TGS renew or validate request, copy
only the server field from the outer part of the header ticket
to the new ticket. Copying the whole structure causes the
enc_part pointer to be aliased to the header ticket until
krb5_encrypt_tkt_part() is called, resulting in a double-free
if handle_authdata() fails..
