    descriptionThe OpenSSL development team has announced that a security audit by A.L. Digital Ltd and The Bunker, under the DARPA CHATS program, has revealed remotely exploitable buffer overflow conditions in the OpenSSL code. Additionally, the ASN1 parser in OpenSSL has a potential DoS attack independently discovered by Adi Stav and James Yonan. CAN-2002-0655 references overflows in buffers used to hold ASCII representations of integers on 64 bit platforms. CAN-2002-0656 references buffer overflows in the SSL2 server implementation (by sending an invalid key to the server) and the SSL3 client implementation (by sending a large session id to the client). The SSL2 issue was also noticed by Neohapsis, who have privately demonstrated exploit code for this issue. CAN-2002-0659 references the ASN1 parser DoS issue. These vulnerabilities have been addressed for Debian 3.0 (woody) in openssl094_0.9.4-6.woody.2, openssl095_0.9.5a-6.woody.1 and openssl_0.9.6c-2.woody.1. These vulnerabilities are also present in Debian 2.2 (potato). Fixed packages are available in openssl094_0.9.4-6.potato.2 and openssl_0.9.6c-0.potato.4. A worm is actively exploiting this issue on internet-attached hosts; we recommend you upgrade your OpenSSL as soon as possible. Note that you must restart any daemons using SSL. (E.g., ssh or ssl-enabled apache.) If you are uncertain which programs are using SSL you may choose to reboot to ensure that all running daemons are using the new libraries.

    descriptionUpdated OpenSSL packages are available which fix several serious buffer overflow vulnerabilities. OpenSSL is a commercial-grade, full-featured, and Open Source toolkit which implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. A security audit of the OpenSSL code sponsored by DARPA found several buffer overflows in OpenSSL which affect versions 0.9.7 and 0.9.6d and earlier : 1. The master key supplied by a client to an SSL version 2 server could be oversized, causing a stack-based buffer overflow. This issue is remotely exploitable. Services that have SSLv2 disabled would not be vulnerable to this issue. (CVE-2002-0656) 2. The SSLv3 session ID supplied to a client from a malicious server could be oversized and overrun a buffer. This issue looks to be remotely exploitable. (CVE-2002-0656) 3. Various buffers used for storing ASCII representations of integers were too small on 64 bit platforms. This issue may be exploitable. (CVE-2002-0655) A further issue was found in OpenSSL 0.9.7 that does not affect versions of OpenSSL shipped with Red Hat Linux (CVE-2002-0657). A large number of applications within Red Hat Linux make use the OpenSSL library to provide SSL support. All users are therefore advised to upgrade to the errata OpenSSL packages, which contain patches to correct these vulnerabilities. NOTE : Please read the Solution section below as it contains instructions for making sure that all SSL-enabled processes are restarted after the update is applied. Thanks go to the OpenSSL team and Ben Laurie for providing patches for these issues.

    NASL idMANDRAKE_MDKSA-2002-046.NASL
    descriptionAn audit of the OpenSSL code by A.L. Digital Ltd and The Bunker, under the DARPA program CHATS, discovered a number of vulnerabilities in the OpenSSL code that are all potentially remotely exploitable. From the OpenSSL advisory : 1. The client master key in SSL2 could be oversized and overrun a buffer. This vulnerability was also independently discovered by consultants at Neohapsis (http://www.neohapsis.com/) who have also demonstrated that the vulerability is exploitable. Exploit code is NOT available at this time. 2. The session ID supplied to a client in SSL3 could be oversized and overrun a buffer. 3. The master key supplied to an SSL3 server could be oversized and overrun a stack-based buffer. This issues only affects OpenSSL 0.9.7 with Kerberos enabled. 4. Various buffers for ASCII representations of integers were too small on 64 bit platforms. At the same time, various potential buffer overflows have had assertions added; these are not known to be exploitable. Finally, a vulnerability was found by Adi Stav and James Yonan independently in the ASN1 parser which can be confused by supplying it with certain invalid encodings. There are no known exploits for this vulnerability. All of these vulnerabilities are fixed in OpenSSL 0.9.6f. Patches have been applied to the versions of OpenSSL provided in this update to fix all of these problems, except for the ASN1 vulnerability, which a fix will be provided for once MandrakeSoft has had a chance to QA the new packages. In the meantime, it is is strongly encouraged that all users upgrade to these OpenSSL packages. Update : These new OpenSSL packages are available to additionally fix the ASN1 vulnerability described above. All Mandrake Linux users are encouraged to upgrade to these new packages.
