Subject: VUL-0: systemtap-server code exec
References: bnc#574243
Signed-Off-By: Tony Jones <tonyj@suse.de>
Fix remaining portions of this CVE (part2) still present post release-1.1
This second part is also referred to as CVE-2010-0412
Covers cases such as stap-client -B CC=/bin/rm CFLAGS=/ ... where the
execution is done by make
commit b75067caf1bb416af21473e40c917d953531e9f9
Author: Dave Brolley <brolley@redhat.com>
Date: Mon Jan 18 11:56:13 2010 -0500
Correct client-side quoting issues discovered by fche during the server-side reimplementation.
Also add the test cases to the test suite.
commit 241443ad36a5a2cacb9e8e6f12f808d304835f2a
Author: Dave Brolley <brolley@redhat.com>
Date: Tue Feb 2 08:26:01 2010 -0500
PR 11105: Remaining client-side problems:
stap-client: Correct handling of embedded newlines in arguments.
server_args.exp: Add additional cases discovered by fche and by fuzzing.
commit 4240be911e37b817727ecb33f321f0ea389ede61
Author: Dave Brolley <brolley@redhat.com>
Date: Mon Feb 15 15:01:28 2010 -0500
Don't pass client-only options to the server.
Also correct parsing of the --server option.
commit d2334a2233f4efd055dab021c603f7c046730a66
Author: Dave Brolley <brolley@redhat.com>
Date: Tue Feb 2 14:08:31 2010 -0500

Subject: VUL-1: systemtap: DoS issue in __get_argv() function
References: bnc#577382
Signed-Off-By: Tony Jones <tonyj@suse.de>
commit a2d399c87a642190f08ede63dc6fc434a5a8363a
Author: Josh Stone <jistone@redhat.com>

PR11234: Rewrite __get_argv without embedded-C
We now implement __get_argv's string building in pure stap script.
Also, every argument is now quoted, which is different than before, but
it's much more robust about handling special characters.

Subject: Three SystemTap-1.0 denial of service issues
References: CVE-2009-2911, BNC#548361
Upstream: yes
Three denial of service flaws were found in the SystemTap
instrumentation system of version 1.0, when the --unprivileged mode was
activated:
b, Kernel stack frame overflow allows local attackers to cause denial
of service via specially-crafted user-provided DWARF information.

PR11195: Prevent all nested argument substitution
Our existing protection only made sure that the first token in a
substitution wasn't a nested substitution. That's not sufficient when
there could be multiple tokens involved. This patch makes sure that no
nested tokens are ever allowed to be argument substitutions.
This also adds a cursor_suspended_line/column and resets the main
cursor_line/column to the beginning of the substitution, so errors will
point a little closer to the right place.
