-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : openssl SUMMARY : Several vulnerabilities DATE : 2002-07-31 11:54:00 ID : CLA-2002:513 RELEVANT RELEASES : 6.0, 7.0, 8 - ------------------------------------------------------------------------- DESCRIPTION OpenSSL implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as full-strength general purpose cryptography functions. It's used (as a library) by several projects, like Apache, OpenSSH, Bind, OpenLDAP and many others clients and servers programs. While conducting a security review of OpenSSL under the DARPA CHATS program[1], A.L Digital and The Bunker found some buffer overflow vulnerabilities in OpenSSL prior to (and including) versions 0.9.6e and 0.9.7-beta2 (development). Neophasis consultants indenpendently discovered one of these buffer overflows and demonstrated that it was exploitable, although the exploit is not released at this time. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2002-0655, CAN-2002-0656 and CAN-2002-0657 to these issues. Adi Stav <stavat_private> and James Yonan <jimat_private> independently found another vulnerability which affects the ASN.1 parser. This update fix these vulnerabilites and also adds various sanity checks to avoid potential buffer overflows. A complete advisory provided by the OpenSSL team is available[2] in their website. SOLUTION All openssl users should upgrade. Please notice that in order to complete the upgrade process, you must restart all running aplications that are linked to openssl libraries after the new packages are installed. You can see a list of such applications using the lsof utility, as seen below: # lsof | egrep '(libcrypto|libssl)' Services (like apache and openssh daemons) can be restarted using the "service" command. For example: # service httpd restart # service openssh restart REFERENCES: 1.http://www.darpa.mil/ito/research/chats 2.http://www.openssl.org/news/secadv_20020730.txt 3.http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0655 4.http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0656 5.http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0657 DIRECT DOWNLOAD LINKS TO THE UPDATED PACKAGES ftp://atualizacoes.conectiva.com.br/6.0/RPMS/openssl-0.9.6-4U60_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/6.0/RPMS/openssl-devel-0.9.6-4U60_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/6.0/SRPMS/openssl-0.9.6-4U60_3cl.src.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/openssl-0.9.6a-3U70_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/openssl-devel-0.9.6a-3U70_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/openssl-devel-static-0.9.6a-3U70_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/openssl-doc-0.9.6a-3U70_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/openssl-progs-0.9.6a-3U70_3cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/SRPMS/openssl-0.9.6a-3U70_3cl.src.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/openssl-0.9.6c-2U8_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/openssl-devel-0.9.6c-2U8_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/openssl-devel-static-0.9.6c-2U8_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/openssl-doc-0.9.6c-2U8_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/openssl-progs-0.9.6c-2U8_1cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/SRPMS/openssl-0.9.6c-2U8_1cl.src.rpm ADDITIONAL INSTRUCTIONS Users of Conectiva Linux version 6.0 or higher may use apt to perform upgrades of RPM packages: - add the following line to /etc/apt/sources.list if it is not there yet (you may also use linuxconf to do this): rpm [cncbr] ftp://atualizacoes.conectiva.com.br 6.0/conectiva updates (replace 6.0 with the correct version number if you are not running CL6.0) - run: apt-get update - after that, execute: apt-get upgrade Detailed instructions reagarding the use of apt and upgrade examples can be found at http://distro.conectiva.com.br/atualizacoes/#apt?idioma=en - ------------------------------------------------------------------------- All packages are signed with Conectiva's GPG key.
