                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           apache
Advisory ID:            MDKSA-2002:039
Date:                   June 20th, 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:

 A Denial of Service attack was discovered by Mark Litchfield in the
 Apache webserver.  As well, while investigating this problem, the
 Apache Software Foundation discovered that the code for handling
 invalid requests that use chunked encoding may also allow arbitrary
 code to be executed on 64bit architectures.

 All versions of Apache prior to 1.3.26 and 2.0.37 are vulnerable to
 this problem.  A patched version of Apache is currently available for
 Single Network Firewall 7.2, with patched versions of Apache soon to
 be available for the other supported Mandrake Linux versions.
