FreeBSD Security Advisory FreeBSD-SA-09:08.openssl
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 = FreeBSD-SA-09:08.opensslSecurity Advisory The FreeBSD Project Topic: Remotely exploitable crash in OpenSSL Category: contrib Module: openssl Announced: 2009-04-22 Affects:All supported versions of FreeBSD. Corrected: 2009-04-22 14:07:14 UTC (RELENG_7, 7.2-PRERELEASE) 2009-04-22 14:07:14 UTC (RELENG_7_2, 7.2-RC2) 2009-04-22 14:07:14 UTC (RELENG_7_1, 7.1-RELEASE-p5) 2009-04-22 14:07:14 UTC (RELENG_7_0, 7.0-RELEASE-p12) 2009-04-22 14:07:14 UTC (RELENG_6, 6.4-STABLE) 2009-04-22 14:07:14 UTC (RELENG_6_4, 6.4-RELEASE-p4) 2009-04-22 14:07:14 UTC (RELENG_6_3, 6.3-RELEASE-p10) CVE Name: CVE-2009-0590 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 FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The function ASN1_STRING_print_ex is often used to print the contents of an SSL certificate. II. Problem Description The function ASN1_STRING_print_ex does not properly validate the lengths of BMPString or UniversalString objects before attempting to print them. III. Impact An application which attempts to print a BMPString or UniversalString which has an invalid length will crash as a result of OpenSSL accessing invalid memory locations. This could be used by an attacker to crash a remote application. IV. Workaround No workaround is available, but applications which do not use the ASN1_STRING_print_ex function (either directly or indirectly) are not affected. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 6-STABLE, or 7-STABLE, or to the RELENG_7_2, RELENG_7_1, RELENG_7_0, 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, 7.0, 7.1, and 7.2 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

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 VI.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 = FreeBSD-SA-09:07.libc Security Advisory The FreeBSD Project Topic: Information leak in db(3) Category: core Module: libc Announced: 2009-04-22 Credits:Jaakko Heinonen, Xin LI Affects:All supported versions of FreeBSD. Corrected: 2009-04-11 15:19:26 UTC (RELENG_7, 7.2-PRERELEASE) 2009-04-22 14:07:14 UTC (RELENG_7_1, 7.1-RELEASE-p5) 2009-04-22 14:07:14 UTC (RELENG_7_0, 7.0-RELEASE-p12) 2009-04-11 15:21:11 UTC (RELENG_6, 6.4-STABLE) 2009-04-22 14:07:14 UTC (RELENG_6_4, 6.4-RELEASE-p4) 2009-04-22 14:07:14 UTC (RELENG_6_3, 6.3-RELEASE-p10) 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 FreeBSD's C library (libc) contains code for creating and accessing Berkeley DB 1.85 database files. Such databases are used extensively in FreeBSD; for example, the system password files (/etc/passwd and /etc/master.passwd) are normally accessed via their database files (/etc/pwd.db and /etc/spwd.db). II. Problem Description Some data structures used by the database interface code are not properly initialized when allocated. III. Impact Programs using the db(3) interface to create Berkeley database files may leak sensitive information into database files. If those files can be read by other users, this may result in the disclosure of sensitive information such as login credentials. IV. Workaround No workaround is available, but systems without untrusted local users are probably not affected (since remote attackers will in most cases not be able to read such database files). V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 6-STABLE, or 7-STABLE, or to the RELENG_7_1, RELENG_7_0, 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, 7.0, and 7.1 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-09:07/libc.patch # fetch http://security.FreeBSD.org/patches/SA-09:07/libc.patch.asc b) Execute the following commands as root: # cd /usr/src # patch /path/to/patch # cd /usr/src/lib/libc # make obj make depend 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 NOTE: System administrators may wish to rebuild any system database files which were created prior to applying this patch in case they contain sensitive information.
