-
-Some versions of clang erroneously detect use of an uninitialized
-variable reply_len in kcmio_call() when building on non-Mac platforms.
-Initialize it to work around this warning.

-Subject: [PATCH 2/4] Fix IAKERB context aliasing bugs [CVE-2015-2696]
-
-The IAKERB mechanism currently replaces its context handle with the
-krb5 mechanism handle upon establishment, under the assumption that
-most GSS functions are only called after context establishment. This
-assumption is incorrect, and can lead to aliasing violations for some
-programs. Maintain the IAKERB context structure after context
-establishment and add new IAKERB entry points to refer to it with that
-type. Add initiate and established flags to the IAKERB context
-structure for use in gss_inquire_context() prior to context
-establishment.
-
-CVE-2015-2696:
-
-In MIT krb5 1.9 and later, applications which call
-gss_inquire_context() on a partially-established IAKERB context can
-cause the GSS-API library to read from a pointer using the wrong type,
-generally causing a process crash. Java server applications using the
-native JGSS provider are vulnerable to this bug. A carefully crafted
-IAKERB packet might allow the gss_inquire_context() call to succeed
-with attacker-determined results, but applications should not make
-access control decisions based on gss_inquire_context() results prior
-to context establishment.

-Subject: [PATCH 4/4] Fix IAKERB context export/import [CVE-2015-2698]
-
-The patches for CVE-2015-2696 contained a regression in the newly
-added IAKERB iakerb_gss_export_sec_context() function, which could
-cause it to corrupt memory. Fix the regression by properly
-dereferencing the context_handle pointer before casting it.
-
-Also, the patches did not implement an IAKERB gss_import_sec_context()
-function, under the erroneous belief that an exported IAKERB context
-would be tagged as a krb5 context. Implement it now to allow IAKERB
-contexts to be successfully exported and imported after establishment.
-
-CVE-2015-2698:
-
-In any MIT krb5 release with the patches for CVE-2015-2696 applied, an
-application which calls gss_export_sec_context() may experience memory
-corruption if the context was established using the IAKERB mechanism.
-Historically, some vulnerabilities of this nature can be translated
-into remote code execution, though the necessary exploits must be
-tailored to the individual application and are usually quite
-complicated.

-Subject: [PATCH 1/4] Fix SPNEGO context aliasing bugs [CVE-2015-2695]
-
-The SPNEGO mechanism currently replaces its context handle with the
-mechanism context handle upon establishment, under the assumption that
-most GSS functions are only called after context establishment. This
-assumption is incorrect, and can lead to aliasing violations for some
-programs. Maintain the SPNEGO context structure after context
-establishment and refer to it in all GSS methods. Add initiate and
-opened flags to the SPNEGO context structure for use in
-gss_inquire_context() prior to context establishment.
-

-In MIT krb5 1.5 and later, applications which call
-gss_inquire_context() on a partially-established SPNEGO context can
-cause the GSS-API library to read from a pointer using the wrong type,
-generally causing a process crash. This bug may go unnoticed, because
-the most common SPNEGO authentication scenario establishes the context
-after just one call to gss_accept_sec_context(). Java server
-applications using the native JGSS provider are vulnerable to this
-bug. A carefully crafted SPNEGO packet might allow the
-gss_inquire_context() call to succeed with attacker-determined
-results, but applications should not make access control decisions
-based on gss_inquire_context() results prior to context establishment.

-Subject: [PATCH 3/4] Fix build_principal memory bug [CVE-2015-2697]
-
-In build_principal_va(), use k5memdup0() instead of strdup() to make a
-copy of the realm, to ensure that we allocate the correct number of
-bytes and do not read past the end of the input string. This bug
-affects krb5_build_principal(), krb5_build_principal_va(), and
-krb5_build_principal_alloc_va(). krb5_build_principal_ext() is not
-affected.

-CVE-2015-2697:
-
-In MIT krb5 1.7 and later, an authenticated attacker may be able to
-cause a KDC to crash using a TGS request with a large realm field
-beginning with a null byte. If the KDC attempts to find a referral to
-answer the request, it constructs a principal name for lookup using
-krb5_build_principal() with the requested realm. Due to a bug in this
-function, the null byte causes only one byte be allocated for the
-realm field of the constructed principal, far less than its length.
-Subsequent operations on the lookup principal may cause a read beyond
-the end of the mapped memory region, causing the KDC process to crash.

-Subject: kerb: Fix LDAP null deref on empty arg [CVE-2016-3119]
-From: Greg Hudson
-
-In the LDAP KDB module's process_db_args(), strtok_r() may return NULL
-if there is an empty string in the db_args array. Check for this case
-and avoid dereferencing a null pointer.
-
-CVE-2016-3119:
-
-In MIT krb5 1.6 and later, an authenticated attacker with permission
-to modify a principal entry can cause kadmind to dereference a null
-pointer by supplying an empty DB argument to the modify_principal
-command, if kadmind is configured to use the LDAP KDB module.

-Subject: [PATCH] Fix S4U2Self KDC crash when anon is restricted
-
-cherry-picked from 93b4a6306a0026cf1cc31ac4bd8a49ba5d034ba7 upstream
-
-In validate_as_request(), when enforcing restrict_anonymous_to_tgt,
-use client.princ instead of request->client; the latter is NULL when
-validating S4U2Self requests.
-
-CVE-2016-3120:
-
-In MIT krb5 1.9 and later, an authenticated attacker can cause krb5kdc
-to dereference a null pointer if the restrict_anonymous_to_tgt option
-is set to true, by making an S4U2Self request.
