                Mandrake Linux Security Update Advisory 
________________________________________________________________________ 


Package name: openssl 
Advisory ID: MDKSA-2002:046 
Date: July 30th, 2002 
Affected versions: 7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1, 
                        Single Network Firewall 7.2 
________________________________________________________________________ 


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.
