U radu programskog paketa MyProxy, distribuiranog s operacijskim sustavima Fedora 13 i 14, uočena je sigurnosna nepravilnost. Riječ je o paketu otvorenog koda koji upravlja ključevima X.509 infrastrukture javnog ključa i certifikatima. Ranjivost je posljedica nepravilne provjere certifikata u "myproxy-logon" aplikaciji. Napadač može iskoristiti propust za otkrivanje korisničkih lozinki putem MITM (eng. man-in-the-middle) napada. Zlouporaba podrazumijeva navođenje korisnika na spajanje na zlonamjerni myproxy poslužitelj. Ispravljeni propusti uključeni su u nove inačice koje se korisnicima savjetuju na korištenje.

--------------------------------------------------------------------------------
Name : myproxy
Product : Fedora 13
Version : 5.3
Release : 1.fc13
URL : http://grid.ncsa.illinois.edu/myproxy/
Summary : Manage X.509 Public Key Infrastructure (PKI) security
credentials
Description :
MyProxy is open source software for managing X.509 Public Key Infrastructure
(PKI) security credentials (certificates and private keys). MyProxy
combines an online credential repository with an online certificate
authority to allow users to securely obtain credentials when and where needed.
Users run myproxy-logon to authenticate and obtain credentials, including
trusted CA certificates and Certificate Revocation Lists (CRLs).
--------------------------------------------------------------------------------
Update Information:
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:
http://grid.ncsa.illinois.edu/myproxy/security/myproxy-adv-2011-01.txt
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=7103)
* 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=7098)
* 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=7119)
* make all Globus Usage library errors non-fatal
(http://bugzilla.globus.org/bugzilla/show_bug.cgi?id=7111)
