Fedora 13 : myproxy-5.3-1.fc13 (2011-0512)

Synopsis :

The remote Fedora host is missing a security update.

Description :

Release 5.3 fixes a myproxy-logon security bug in MyProxy versions
5.0-5.2 that disabled server identity verification :

The myproxy-logon program in MyProxy versions 5.0 through 5.2 does not
enforce the check that the myproxy-server's certificate contains the
expected hostname or identity. The impacted MyProxy versions are
included in Globus Toolkit releases 5.0.0-5.0.2. This issue is
addressed in MyProxy 5.3.

Full details are available:

Other changes in this release :

- if myproxy-logon GSI mutual authentication with the
myproxy-server fails, try again with client-side
anonymous authentication, in case the client-side GSI
credentials are unacceptable to the myproxy-server (for
example, signed by an untrusted CA), but the
myproxy-server would accept an anonymous client
(http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=710
3)

- fix configure checks for globus_usage_stats_send,
globus_usage_stats_send_array, and
globus_gsi_proxy_handle_set_extensions when installing
without existing Globus libraries in LD_LIBRARY_PATH
(http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=7
098)

- in myproxy-server-setup, look in /sbin and /usr/sbin
for chkconfig or update-rc.d in case they're not in
PATH

- add certificate_issuer_subca_certfile option in
myproxy-server.config
(http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=7
119)

- make all Globus Usage library errors non-fatal
(http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=7
