                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           openssl
Advisory ID:            MDKSA-2002:046-1
Date:                   August 6th, 2002
Original Advisory 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.

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.
