                 Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           kernel
 Advisory ID:            MDKSA-2004:087
 Date:                   August 26th, 2004

 Affected versions:      10.0, 9.1, 9.2, Corporate Server 2.1,
                         Multi Network Firewall 8.2
 ______________________________________________________________________

 Problem Description:

 A race condition was discovered in the 64bit file offset handling by
 Paul Starzetz from iSEC.  The file offset pointer (f_pos) is changed
 during reading, writing, and seeking through a file in order to point
 to the current position of a file.  The value conversion between both
 the 32bit and 64bit API in the kernel, as well as access to the f_pos
 pointer, is defective.  As a result, a local attacker can abuse this
 vulnerability to gain access to uninitialized kernel memory, mostly
 via entries in the /proc filesystem.  This kernel memory can possibly
 contain information like the root password, and other sensitive data.

 The updated kernel packages provided are patched to protect against
 this vulnerability, and all users are encouraged to upgrade
 immediately.
