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

PACKAGE : kernel
SUMMARY : Fixes for kernel vulnerabilities
DATE : 2004-10-26 18:05:00
ID : CLA-2004:879
RELEVANT
RELEASES : 10

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

DESCRIPTION
The Linux kernel is responsible for handling the basic functions of
the GNU/Linux operating system.

This announcement fixes a vulnerability in the Linux kernel which
could allow a local attacker to obtain sensitive information due to
an issue when handling 64-bit file offset pointers. A local attacker
could exploit this vulnerability to read portions of the kernel's
memory.

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. 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.
