[guru] FreeBSD biztonsagi frissitesek
DATE: Tue, 05 Jan 2010 00:43:06 +0100
Az SSL/TLS protokollok session renegotiation sebezhetőségére a FreeBSD
OpenSSL csomagjában letiltották az újraegyeztetést, hiszen ezt csak kevesen
használják.
Az rtld a környezeti változók kezelésének átalakítása miatt már nem
távolít el minden veszélyes környezeti változót, így setuid root programok
segítségével root jog szerezhető.
A freebsd-update a /var/db/freebsd-update munkakönyvtárát olyan jogokkal
hozza létre, hogy azt mindenki láthatja. Előfordulhat, hogy az alá mentett
backup állományokhoz a támadó hozzáférhet, pedig az eredeti helyén nem
tehette volna meg.

CVE Name: CVE-2009-3555
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:http://security.FreeBSD.org/>.
I. Background
The SSL (Secure Sockets Layer) and TLS (Transport Layer Security) protocols
provide a secure communications layer over which other protocols can be
utilized. The most widespread use of SSL/TLS is to add security to the
HTTP protocol, thus producing HTTPS.
FreeBSD includes software from the OpenSSL Project which implements SSL
and TLS.
II. Problem Description
The SSL version 3 and TLS protocols support session renegotiation without
cryptographically tying the new session parameters to the old parameters.
III. Impact
An attacker who can intercept a TCP connection being used for SSL or TLS
can cause the initial session negotiation to take the place of a session
renegotiation. This can be exploited in several ways, including:
* Causing a server to interpret incoming messages as having been sent
under the auspices of a client SSL key when in fact they were not;
* Causing a client request to be appended to an attacker-supplied
request, potentially revealing to the attacker the contents of the client
request (including any authentication parameters); and
* Causing a client to receive a response to an attacker-supplied request
instead of a response to the request sent by the client.
IV. Workaround
No workaround is available.
V. Solution
NOTE WELL: This update causes OpenSSL to reject any attempt to renegotiate
SSL / TLS session parameters. As a result, connections in which the other
party attempts to renegotiate session parameters will break. In practice,
however, session renegotiation is a rarely-used feature, so disabling this
functionality is unlikely to cause problems for most systems.
Perform one of the following:
1) Upgrade your vulnerable system to 6-STABLE, 7-STABLE, or 8-STABLE, or to
the RELENG_8_0, RELENG_7_2, RELENG_7_1, RELENG_6_4, or RELENG_6_3 security
branch dated after the correction date.
2) To patch your present system:
The following patches have been verified to apply to FreeBSD 6.3, 6.4,
7.1, 7.2, and 8.0 systems.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
# fetch http://security.FreeBSD.org/patches/SA-09:15/ssl.patch
# fetch http://security.FreeBSD.org/patches/SA-09:15/ssl.patch.asc
b) Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
# cd /usr/src/secure/lib/libcrypto
# make obj && make depend && make includes && make && make install
NOTE: On the amd64 platform, the above procedure will not update the
lib32 (i386 compatibility) libraries. On amd64 systems where the i386
compatibility libraries are used, the operating system should instead
be recompiled as described in
<URL:http://www.FreeBSD.org/handbook/makeworld.html>

FreeBSD-SA-09:16.rtld Security Advisory
The FreeBSD Project
Topic: Improper environment sanitization in rtld(1)
Category: core
Module: rtld
Announced: 2009-12-03
Affects: FreeBSD 7.0 and later.
Corrected: 2009-12-01 02:59:22 UTC (RELENG_8, 8.0-STABLE)
2009-12-03 09:18:40 UTC (RELENG_8_0, 8.0-RELEASE-p1)

2009-12-03 09:18:40 UTC (RELENG_7_1, 7.1-RELEASE-p9)
CVE Name: CVE-2009-4146, CVE-2009-4147
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:http://security.FreeBSD.org/>.
I. Background
The run-time link-editor, rtld, links dynamic executable with their
needed libraries at run-time. It also allows users to explicitly
load libraries via various LD_ environmental variables.
II. Problem Description
When running setuid programs rtld will normally remove potentially
dangerous environment variables. Due to recent changes in FreeBSD
environment variable handling code, a corrupt environment may
result in attempts to unset environment variables failing.
III. Impact
An unprivileged user who can execute programs on a system can gain
the privileges of any setuid program which he can run. On most
systems configurations, this will allow a local attacker to execute
code as the root user.
IV. Workaround
No workaround is available, but systems without untrusted local users,
where all the untrusted local users are jailed superusers, and/or where
untrusted users cannot execute arbitrary code (e.g., due to use of read
only and noexec mount options) are not affected.
Note that "untrusted local users" include users with the ability to
upload and execute web scripts (CGI, PHP, Python, Perl etc.), as they
may be able to exploit this issue.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to 7-STABLE or 8-STABLE,
or to the RELENG_8_0, RELENG_7_2, or RELENG_7_1 security branch dated
after the correction date.
2) To patch your present system:
The following patches have been verified to apply to FreeBSD 7.1, 7.2,
and 8.0 systems.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.

# fetch http://security.FreeBSD.org/patches/SA-09:16/rtld.patch

b) Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
# cd /usr/src/libexec/rtld-elf

NOTE: On the amd64 platform, the above procedure will not update the
ld-elf32.so.1 (i386 compatibility) run-time link-editor (rtld). On
amd64 systems where the i386 rtld are installed, the operating system

FreeBSD-SA-09:17.freebsd-update Security Advisory
The FreeBSD Project
Topic: Inappropriate directory permissions in freebsd-update(8)
Category: core
Module: usr.sbin
Announced: 2009-12-03
Credits: KAMADA Ken'ichi
Affects: All supported versions of FreeBSD.
Corrected: 2009-12-03 09:18:40 UTC (RELENG_8, 8.0-STABLE)

2009-12-03 09:18:40 UTC (RELENG_6_3, 6.3-RELEASE-p14)
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:http://security.FreeBSD.org/>.
I. Background
The freebsd-update(8) utility is used to fetch, install, and rollback
updates to the FreeBSD base system, and also to upgrade from one FreeBSD
release to another.
II. Problem Description
When downloading updates to FreeBSD via 'freebsd-update fetch' or
'freebsd-update upgrade', the freebsd-update(8) utility copies currently
installed files into its working directory (/var/db/freebsd-update by
default) both for the purpose of merging changes to configuration files
and in order to be able to roll back installed updates.
The default working directory used by freebsd-update(8) is normally
created during the installation of FreeBSD with permissions which allow
all local users to see its contents, and freebsd-update(8) does not take
any steps to restrict access to files stored in said directory.
III. Impact
A local user can read files which have been updated by freebsd-update(8),
even if those files have permissions which would normally not allow users
to read them. In particular, on systems which have been upgraded using
'freebsd-update upgrade', local users can read freebsd-update's backed-up
copy of the master password file.
IV. Workaround
Set the permissions on the freebsd-update(8) working directory to not
allow unprivileged users to read said directory:
# chmod 0700 /var/db/freebsd-update
Note that if freebsd-update(8) is run using the '-d workdir' option, the
directory which should have its permissions adjusted will be different.
V. Solution
Perform one of the following:
1) Upgrade your vulnerable system to 6-STABLE, 7-STABLE or 8-STABLE,
or to the RELENG_8_0, RELENG_7_2, RELENG_7_1, RELENG_6_4, or
RELENG_6_3 security branch dated after the correction date.
2) To patch your present system:
The following patch has been verified to apply to FreeBSD 6.3, 6.4,
7.1, 7.2, and 8.0 systems.

# fetch http://security.FreeBSD.org/patches/SA-09:17/freebsd-update.patch
# fetch http://security.FreeBSD.org/patches/SA-09:17/freebsd-update.patch.asc
b) Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
# cd /usr/src/usr.sbin/freebsd-update
# make obj && make depend && make && make install
# chmod 0700 /var/db/freebsd-update

0. Revision History
v1.0 2009-12-03 Initial release.
