ELSA-2015-0439 - krb5 security, bug fix and enhancement update

Type:SECURITY
Severity:MODERATE
Release Date:2015-03-11

Description


[1.12.2-14]
- fix for kinit -C loops (#1184629, MIT/krb5 issue 243, 'Do not
loop on principal unknown errors').

[1.12.2-13]
- fix for CVE-2014-5352 (#1179856) 'gss_process_context_token()
incorrectly frees context (MITKRB5-SA-2015-001)'
- fix for CVE-2014-9421 (#1179857) 'kadmind doubly frees partial
deserialization results (MITKRB5-SA-2015-001)'
- fix for CVE-2014-9422 (#1179861) 'kadmind incorrectly
validates server principal name (MITKRB5-SA-2015-001)'
- fix for CVE-2014-9423 (#1179863) 'libgssrpc server applications
leak uninitialized bytes (MITKRB5-SA-2015-001)'

[1.12.2-12]
- fix for CVE-2014-5354 (#1174546) 'krb5: NULL pointer
dereference when using keyless entries'

[1.12.2-11]
- fix for CVE-2014-5353 (#1174543) 'Fix LDAP misused policy
name crash'

[1.12.2-10]
- In ksu, without the -e flag, also check .k5users (#1105489)
When ksu was explicitly told to spawn a shell, a line in .k5users which
listed '*' as the allowed command would cause the principal named on the
line to be considered as a candidate for authentication.
When ksu was not passed a command to run, which implicitly meant that
the invoking user wanted to run the target user's login shell, knowledge
that the principal was a valid candidate was ignored, which could cause
a less optimal choice of the default target principal.
This doesn't impact the authorization checks which we perform later.
Patch by Nalin Dahyabhai

[1.12.2-9]
- Undo libkadmclnt SONAME change (from 8 to 9) which originally
happened in the krb5 1.12 rebase (#1166012) but broke
rubygem-rkerberos (sort of ruby language bindings for
libkadmclnt&co.) dependicies, as side effect of
rubygem-rkerberos using private interfaces in libkadmclnt.

[1.12.2-8]
- fix the problem where the %license file has been a dangling symlink
- ksu: pull in fix from pull #206 to avoid breakage when the
default_ccache_name doesn't include a cache type as a prefix
- ksu: pull in a proposed fix for pull #207 to avoid breakage when the
invoking user doesn't already have a ccache

defined (RT#7947)

[1.12.2-6]
- backport patch to make the client skip checking the server's reply
address when processing responses to password-change requests, which
between NAT and upcoming HTTPS support, can cause us to erroneously
report an error to the user when the server actually reported success
(RT#7886)
- backport support for accessing KDCs and kpasswd services via HTTPS
proxies (marked by being specified as https URIs instead as hostnames
or hostname-and-port), such as the one implemented in python-kdcproxy
(RT#7929, #109919), and pick up a subsequent patch to build HTTPS
as a plugin

[1.12.2-5]
- backport fix for trying all compatible keys when not being strict about
acceptor names while reading AP-REQs (RT#7883, #1078888)

it's declared (#1059730,#1084068,#1109102)

[1.12.2-4]
- kpropd hasn't bothered with -S since 1.11; stop trying to use that flag
in the systemd unit file

strdup() call (#1132062)
