Mandrake Linux Advisory: openssl

Jul 31, 2002, 12:49 (2 Talkback[s])

                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.
