Release Notes - Heimdal - Version Heimdal 7.7

Bug fixes

  • PKCS#11 hcrypto back-end
    . initialize the p11_module_load function list
    . verify that not only is a mechanism present but that its mechanism
    info states that it offers the required encryption, decryption or
    digest services

  • krb5:
    . Starting with 7.6, Heimdal permitted requesting authenticated
    anonymous tickets. However, it did not verify that a KDC in fact
    returned an anonymous ticket when one was requested.
    . Cease setting the KDCOption reaquest_anonymous flag when issuing
    S4UProxy (constrained delegation) TGS requests.
    . when the Win2K PKINIT compatibility option is set, do
    not require krbtgt otherName to match when validating KDC
    . set PKINIT_BTMM flag per Apple implementation
    . use memset_s() instead of memset()

  • kdc:
    . When generating KRB5SignedPath in the AS, use the reply client name
    rather than the one from the request, so validation will work
    correctly in the TGS.
    . allow checksum of PA-FOR-USER to be HMAC_MD5. Even if TGT used
    an enctype with a different checksum. Per [MS-SFU] 2.2.1
    PA-FOR-USER the checksum is always HMAC_MD5, and that's what
    Windows and MIT clients send.

    In Heimdal both the client and kdc use instead the
    checksum of the TGT, and therefore work with each other
    but Windows and MIT clients fail against Heimdal KDC.

    Both Windows and MIT KDC would allow any keyed checksum
    to be used so Heimdal client work fine against it.

    Change Heimdal KDC to allow HMAC_MD5 even for non RC4
    based TGT in order to support per-spec clients.
    . use memset_s() instead of memset()
    . Detect Heimdal 1.0 through 7.6 clients that issue S4UProxy
    (constrained delegation) TGS Requests with the request
    anonymous flag set. These requests will be treated as
    S4UProxy requests and not anonymous requests.

  • HDB:
    . Set SQLite3 backend default page size to 8KB.
    . Add hdb_set_sync() method

  • kadmind:
    . disable HDB sync during database load avoiding unnecessary disk i/o.

  • ipropd:
    . disable HDB sync during receive_everything. Doing an fsync
    per-record when receiving the complete HDB is a performance
    disaster. Among other things, if the HDB is very large, then
    one slave receving a full HDB can cause other slaves to timeout
    and, if HDB write activity is high enough to cause iprop log
    truncation, then also need full syncs, which leads to a cycle of
    full syncs for all slaves until HDB write activity drops.
    Allowing the iprop log to be larger helps, but improving
    receive_everything() performance helps even more.

  • kinit:
    . Anonymous PKINIT tickets discard the realm information used
    to locate the issuing AS. Store the issuing realm in the
    credentials cache in order to locate a KDC which can renew them.
    . Do not leak the result of krb5_cc_get_config() when determining
    anonymous PKINIT start realm.

  • klist:
    . Show transited-policy-checked, ok-as-delegate and anonymous
    flags when listing credentials.

  • tests:
    . Regenerate certs so that they expire before the 2038 armageddon
    so the test suite will pass on 32-bit operating systems until the
    underlying issues can be resolved.

  • Solaris:
    . Define _STDC_C11_BCI for memset_s prototype

  • build tooling:
    . Convert from python 2 to python 3

  • documentation
    . rename verify-password to verify-password-quality
    . hprop default mode is encrypt
    . kadmind "all" permission does not include "get-keys"
    . verify-password-quality might not be stateless
