-Subject: [PATCH] Return only new keys in randkey [CVE-2014-5351]
-
-In kadmind's randkey operation, if a client specifies the keepold
-flag, do not include the preserved old keys in the response.
-
-CVE-2014-5351:
-
-An authenticated remote attacker can retrieve the current keys for a
-service principal when generating a new set of keys for that
-principal.  The attacker needs to be authenticated as a user who has
-the elevated privilege for randomizing the keys of other principals.
-
-Normally, when a Kerberos administrator randomizes the keys of a
-service principal, kadmind returns only the new keys.  This prevents
-an administrator who lacks legitimate privileged access to a service
-from forging tickets to authenticate to that service.  If the
-"keepold" flag to the kadmin randkey RPC operation is true, kadmind
-retains the old keys in the KDC database as intended, but also
-unexpectedly returns the old keys to the client, which exposes the
-service to ticket forgery attacks from the administrator.
-
-A mitigating factor is that legitimate clients of the affected service
-will start failing to authenticate to the service once they begin to
-receive service tickets encrypted in the new keys.  The affected
-service will be unable to decrypt the newly issued tickets, possibly
-alerting the legitimate administrator of the affected service.

+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.
+
+CVE-2015-2695:
+
+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.
