Mandrake Linux Advisory: kernel

______________________________________________________________________

                Mandrake Linux Security Update Advisory
______________________________________________________________________

Package name:           kernel
Advisory ID:            MDKSA-2003:014
Date:                   February 5th, 2003

Affected versions:      9.0
______________________________________________________________________

Problem Description:

 An updated kernel for 9.0 is available with a number of bug fixes. 
 Supermount has been completely overhauled and should be solid on all
 systems.  Other fixes include XFS with high memory, a netfilter fix,
 a fix for Sony VAIO DMI, i845 should now work with UDMA, and new 
 support for VIA C3 is included.  Prism24 has been updated so it now 
 works properly on HP laptops and a new ACPI is included, although it is 
 disabled by default for broader compatibility.
 
 This also fixes a security problem that allows non-root users to freeze
 the kernel, and a fix for a vulnerability in O_DIRECT handling that can 
 create a limited information leak where any user on the system with 
 write privilege to the file system from previously deleted files.  This 
 also allows users to create minor file system corruption (this can
 easily be repaired by fsck).
