CONECTIVA LINUX SECURITY ANNOUNCEMENT 
- --------------------------------------------------------------------------

PACKAGE   : kernel
SUMMARY   : Fix for kernel vulnerability
DATE      : 2004-09-27 11:26:00
ID        : CLA-2004:869
RELEVANT
RELEASES  : 9

- -------------------------------------------------------------------------

DESCRIPTION
 The Linux kernel is responsible for handling the basic functions of
 the GNU/Linux operating system.
 
 This announcement fixes a missing[1] Discretionary Access Control
 (DAC) check in the chown system call that allowed a local user to
 change the group ownership of arbitrary files to a group that he or
 she belongs to, leading to a privileges escalation vulnerability.


SOLUTION
 It is recommended that all Conectiva Linux users upgrade the kernel
 package.
 
 IMPORTANT: exercise caution and preparation when upgrading the
 kernel, since it will require a reboot after the new packages are
 installed. In particular, Conectiva Linux 9 will most likely require
 an initrd file (which is automatically created in the /boot directory
 after the new packages are installed). Generic kernel update
 instructions can be obtained in the manuals and in our updates
 page[2]. More detailed instructions are also available in Portuguese
 at our Moin[3] page.
