Problem description

An 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 independantly 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.
