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

PACKAGE   : kernel 2.4
SUMMARY   : Local denial of service vulnerability
DATE      : 2002-12-16 17:41:00
ID        : CLA-2002:553
RELEVANT
RELEASES  : 7.0, 8

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

DESCRIPTION
 The Linux kernel is responsible for handling the basic functions of
 the Conectiva Linux operating system.
 
 Christophe Devine reported[1] a vulnerability in versions prior to
 2.4.20 of the linux kernel that could be exploited by a local
 non-root user to completely "freeze" the machine. A local attacker
 could exploit this vulnerability to cause a Denial of Service (DoS)
 condition. This update fixes this problem.
 
 Please note that the updated kernel packages here listed are
 available in our update servers since November 20, 2002.


SOLUTION
 All users should upgrade the kernel immediately.
 
 IMPORTANT: it is not possible to use apt to apply kernel updates.
 These packages have to be updated manually. Generic kernel update
 instructions can be found in our updates page[2].
 
 Kernel 2.2 users in Conectiva Linux 6.0 and 7.0 are also vulnerable
 to this issue. It is recommended that these users upgrade to the
 latest (2.4) kernel, but updated packages for the 2.2 series are
 being prepared and will be released in a near future.
