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.

24ce5597-acab-11e4-a847-206a8a720317 | krb5 -- Vulnerabilities in kadmind, libgssrpc, gss_process_context_token VU#540092
SO-AND-SO reports:
CVE-2014-5352: In the MIT krb5 libgssapi_krb5 library, after
gss_process_context_token() is used to process a valid context
deletion token, the caller is left with a security context handle
containing a dangling pointer. Further uses of this handle will
result in use-after-free and double-free memory access violations.
libgssrpc server applications such as kadmind are vulnerable as
they can be instructed to call gss_process_context_token().
CVE-2014-9421: If the MIT krb5 kadmind daemon receives invalid XDR
data from an authenticated user, it may perform use-after-free and
double-free memory access violations while cleaning up the partial
deserialization results. Other libgssrpc server applications may
also be vulnerable if they contain insufficiently defensive XDR
functions.
CVE-2014-9422: The MIT krb5 kadmind daemon incorrectly accepts
authentications to two-component server principals whose first
component is a left substring of "kadmin" or whose realm is a left
prefix of the default realm.
CVE-2014-9423: libgssrpc applications including kadmind output
four or eight bytes of uninitialized memory to the network as
part of an unused "handle" field in replies to clients.

a30573dc-4893-11df-a5f9-001641aeabdf | krb5 -- remote denial of service vulnerability
An authenticated remote attacker can causing a denial
of service by using a newer version of the kadmin protocol
than the server supports.
The MIT Kerberos team also reports the cause:
The Kerberos administration daemon (kadmind) can crash
due to referencing freed memory.

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..

No advisory has been released yet.
schpw.c in the kpasswd service in kadmind in MIT Kerberos 5
(aka krb5) before 1.11.3 does not properly validate UDP packets
before sending responses, which allows remote attackers to cause
a denial of service (CPU and bandwidth consumption) via a forged
packet that triggers a communication loop, as demonstrated by
krb_pingpong.nasl, a related issue to CVE-1999-0103.

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.

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.

11bbccbc-03ee-11e0-bcdb-001fc61c2a55 | krb5 -- multiple checksum handling vulnerabilities
The MIT Kerberos team reports:
MIT krb5 clients incorrectly accept an unkeyed checksums
in the SAM-2 preauthentication challenge.
An unauthenticated remote attacker could alter a SAM-2 challenge,
affecting the prompt text seen by the user or the kind of response
sent to the KDC. Under some circumstances, this can negate the
incremental security benefit of using a single-use authentication
mechanism token.
MIT krb5 incorrectly accepts RFC 3961 key-derivation checksums
using RC4 keys when verifying KRB-SAFE messages.
An unauthenticated remote attacker has a 1/256 chance of forging
KRB-SAFE messages in an application protocol if the targeted
pre-existing session uses an RC4 session key. Few application
protocols use KRB-SAFE messages.
