-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 The MIT Kerberos Team announces the availability of MIT Kerberos 5 Release 1.16.1. Please see below for a list of some major changes included, or consult the README file in the source tree for a more detailed list of significant changes.
RETRIEVING KERBEROS 5 RELEASE 1.16.1 ==================================== You may retrieve the Kerberos 5 Release 1.16.1 source from the following URL: https://kerberos.org/dist/ The homepage for the krb5-1.16.1 release is: http://web.mit.edu/kerberos/krb5-1.16/ Further information about Kerberos 5 may be found at the following URL: http://web.mit.edu/kerberos/ and at the MIT Kerberos Consortium web site: https://www.kerberos.org/ DES transition ============== The Data Encryption Standard (DES) is widely recognized as weak. The krb5-1.7 release contains measures to encourage sites to migrate away from using single-DES cryptosystems. Among these is a configuration variable that enables "weak" enctypes, which defaults to "false" beginning with krb5-1.8. Major changes in 1.16.1 (2018-05-03) ==================================== This is a bug fix release. * Fix flaws in LDAP DN checking, including a null dereference KDC crash which could be triggered by kadmin clients with administrative privileges [CVE-2018-5729, CVE-2018-5730]. * Fix a KDC PKINIT memory leak. * Fix a small KDC memory leak on transited or authdata errors when processing TGS requests. * Fix a regression in pkinit_cert_match matching of client certificates containing Microsoft UPN SANs. * Fix a null dereference when the KDC sends a large TGS reply. * Fix "kdestroy -A" with the KCM credential cache type. * Allow validation of Microsoft PACs containing enterprise names. * Fix the handling of capaths "." values. * Fix handling of repeated subsection specifications in profile files (such as when multiple included files specify relations in the same subsection). Major changes in 1.16 (2017-12-05) ================================== Administrator experience: * The KDC can match PKINIT client certificates against the "pkinit_cert_match" string attribute on the client principal entry, using the same syntax as the existing "pkinit_cert_match" profile option. * The ktutil addent command supports the "-k 0" option to ignore the key version, and the "-s" option to use a non-default salt string. * kpropd supports a --pid-file option to write a pid file at startup, when it is run in standalone mode. * The "encrypted_challenge_indicator" realm option can be used to attach an authentication indicator to tickets obtained using FAST encrypted challenge pre-authentication. * Localization support can be disabled at build time with the --disable-nls configure option. Developer experience: * The kdcpolicy pluggable interface allows modules control whether tickets are issued by the KDC. * The kadm5_auth pluggable interface allows modules to control whether kadmind grants access to a kadmin request. * The certauth pluggable interface allows modules to control which PKINIT client certificates can authenticate to which client principals. * KDB modules can use the client and KDC interface IP addresses to determine whether to allow an AS request. * GSS applications can query the bit strength of a krb5 GSS context using the GSS_C_SEC_CONTEXT_SASL_SSF OID with gss_inquire_sec_context_by_oid(). * GSS applications can query the impersonator name of a krb5 GSS credential using the GSS_KRB5_GET_CRED_IMPERSONATOR OID with gss_inquire_cred_by_oid(). * kdcpreauth modules can query the KDC for the canonicalized requested client principal name, or match a principal name against the requested client principal name with canonicalization. Protocol evolution: * The client library will continue to try pre-authentication mechanisms after most failure conditions. * The KDC will issue trivially renewable tickets (where the renewable lifetime is equal to or less than the ticket lifetime) if requested by the client, to be friendlier to scripts. * The client library will use a random nonce for TGS requests instead of the current system time. * For the RC4 string-to-key or PAC operations, UTF-16 is supported (previously only UCS-2 was supported). * When matching PKINIT client certificates, UPN SANs will be matched correctly as UPNs, with canonicalization. User experience: * Dates after the year 2038 are accepted (provided that the platform time facilities support them), through the year 2106. * Automatic credential cache selection based on the client realm will take into account the fallback realm and the service hostname. * Referral and alternate cross-realm TGTs will not be cached, avoiding some scenarios where they can be added to the credential cache multiple times. * A German translation has been added. Code quality: * The build is warning-clean under clang with the configured warning options. * The automated test suite runs cleanly under AddressSanitizer. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUBWuvIbgy6CFdfg3LfAQLlww/+JkOrXjhDac6rtA6hPj5H/RI4AnaxX68Z xCA+wUWhTXvpOUnR+xMUJsIPMCX+b6E1eEg+wZDjnYhPB32k/1o5H+ehrcPSn1/p QxHw5H+Ss8/VU+2WzHgN4AmSo/VVNTGi/2FWTHIx8R2dZh4RotJQ6gDDMnPBzEiz 4nFW1VEqFqXuymgNXi/KBlVnASQjNQuYDuka0DHy7OQVrShSGw1RPBkOOd54yJmQ RCfHYS2DOxI/m7jS+MpwC/kdJRh0u9T+7trut91PkXdpW2ThF2VznW7DfncMhDAg OANgxvtGwVWIq/5zgCl/WlxnTbV0LRadWmM/FWwOkzoKiw/agCJeaOhBfI62y+pK W8CTdxHlMAXT+OnOBcy8QzeWZ9sGobKN/gma0OPpe/A3qBeRvRMsoj441Jn8fUMz 5zP9Pnj1bi86pQQHny+8cJGoG6A1GLYr1KceC8gtOscSjv4cizlOWW8at9QsRBQ/ /i4BCu5AdFQcaqqBDjMr+WHPVpOs+B/zeIH/sbt7vKaCO5jnWFtZZcWbnSIMam09 +PGNT11xLfYYWXZ7fvGl/nc5zUZ3f8BfI9tXFCQBXsu7W3ujEft3qBiRakeBOtR7 EcPGkNTdxndVjvO66szEUj87Jq2Tn2NpHyg/obgvVxtqDpI1Bav1sLYZgjCk0IM2 //oa1n1eYNY= =OTTv -----END PGP SIGNATURE----- _______________________________________________ kerberos-announce mailing list kerberos-annou...@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos-announce ________________________________________________ Kerberos mailing list Kerberos@mit.edu https://mailman.mit.edu/mailman/listinfo/kerberos
