heimdal: don't try to expose nonexistant symbolsFor one reason or another these symbols aren't present so don't try tomake them available for linkage.In the case of libroken these seem to be compatability bits we don'tneed a thus don't compile. For others it seems to rot upstream, butI've not investigated deeply.Reviewed by: cyDifferential Revision: https://reviews.freebsd.org/D44246

heimdal: Fix multiple security vulnerabilitiesThe following issues are patched: - CVE-2022-42898 PAC parse integer overflows - CVE-2022-3437 Overflows and non-constant time leaks in DES{,3} and arcfour - CVE-2021-44758 NULL dereference DoS in SPNEGO acceptors - CVE-2022-44640 Heimdal KDC: invalid free in ASN.1 codec Note that CVE-2022-44640 is a severe vulnerability, possibly a 10.0 on the Common Vulnerability Scoring System (CVSS) v3, as we believe it should be possible to get an RCE on a KDC, which means that credentials can be compromised that can be used to impersonate anyone in a realm or forest of realms. Heimdal's ASN.1 compiler generates code that allows specially crafted DER encodings of CHOICEs to invoke the wrong free function on the decoded structure upon decode error. This is known to impact the Heimdal KDC, leading to an invalid free() of an address partly or wholly under the control of the attacker, in turn leading to a potential remote code execution (RCE) vulnerability. This error affects the DER codec for all extensible CHOICE types used in Heimdal, though not all cases will be exploitable. We have not completed a thorough analysis of all the Heimdal components affected, thus the Kerberos client, the X.509 library, and other parts, may be affected as well. This bug has been in Heimdal's ASN.1 compiler since 2005, but it may only affect Heimdal 1.6 and up. It was first reported by Douglas Bagnall, though it had been found independently by the Heimdal maintainers via fuzzing a few weeks earlier. While no zero-day exploit is known, such an exploit will likely be available soon after public disclosure. - CVE-2019-14870: Validate client attributes in protocol-transition - CVE-2019-14870: Apply forwardable policy in protocol-transition - CVE-2019-14870: Always lookup impersonate client in DBSponsored by: so (philip)Obtained from: so (philip)Tested by: philip, cyMFC after: immediately

Update the existing heimdal implementation for OpenSSL 1.1.Existing work is underway to import a newer version of heimdal, butthis patchset gets us to a fully working tree to enable more widespread testing of OpenSSL 1.1 for now.I've also enabled WARNS=1 for kerberos (which is the reason for thechange in libroken). Having -Werror enabled was useful during the1.1 updates and we probably should have warnings enabled by defaultfor kerberos anyway.This passes make tinderbox, and I have also done some very lightruntime testing on amd64.Reviewed by: bjk, jkim, emasteDifferential Revision: https://reviews.freebsd.org/D17276

- Update FreeBSD Heimdal distribution to version 1.5.1. This also brings several new kerberos related libraries and applications to FreeBSD: o kgetcred(1) allows one to manually get a ticket for a particular service. o kf(1) securily forwards ticket to another host through an authenticated and encrypted stream. o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1) and other user kerberos operations. klist and kswitch are just symlinks to kcc(1) now. o kswitch(1) allows you to easily switch between kerberos credentials if you're running KCM. o hxtool(1) is a certificate management tool to use with PKINIT. o string2key(1) maps a password into key. o kdigest(8) is a userland tool to access the KDC's digest interface. o kimpersonate(8) creates a "fake" ticket for a service. We also now install manpages for some lirbaries that were not installed before, libheimntlm and libhx509.- The new HEIMDAL version no longer supports Kerberos 4. All users are recommended to switch to Kerberos 5.- Weak ciphers are now disabled by default. To enable DES support (used by telnet(8)), use "allow_weak_crypto" option in krb5.conf.- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings disabled due to the function they use (krb5_get_err_text(3)) being deprecated. I plan to work on this next.- Heimdal's KDC now require sqlite to operate. We use the bundled version and install it as libheimsqlite. If some other FreeBSD components will require it in the future we can rename it to libbsdsqlite and use for these components as well.- This is not a latest Heimdal version, the new one was released while I was working on the update. I will update it to 1.5.2 soon, as it fixes some important bugs and security issues.
