CONECTIVA LINUX SECURITY ANNOUNCEMENT:Fixes for kernel vulnerabilities


Detail
====== 

The Linux kernel is responsible for handling the basic functions of  the GNU/Linux operating system.
 
 This announcement fixes the following vulnerabilities:
 
 1. Local denial of service vulnerability (CAN-2004-0554[1])
 
 Stian Skjelstad found[2] a vulnerability[1] in the fpu controller code that can be used by local
 attackers to cause a denial of service (DoS) on the system.
 
 2. Local memory disclosure vulnerability (CAN-2004-0535[3])
 
 Chris Wright found a vulnerability[3] in the Intel(R) PRO/1000  ethernet card driver that could 
 allow a local attacker to read some  bytes of kernel memory.
 
 3. Sparse vulnerabilities (CAN-2004-0495[4])  
 
 Al Viro, by using Sparse[5] (a code inspection tool), found several  vulnerabilities which, in
 the worst case, might allow local attackers  to obtain root privileges.

DESCRIPTION
 The Linux kernel is responsible for handling the basic functions of  the GNU/Linux operating system.
 
 This announcement fixes the following vulnerabilities:
 
 1. Local denial of service vulnerability (CAN-2004-0554[1])
 
 Stian Skjelstad found[2] a vulnerability[1] in the fpu controller  code that can be used by local attackers to cause a denial of service
 (DoS) on the system.
 
 2. Local memory disclosure vulnerability (CAN-2004-0535[3])
 
 Chris Wright found a vulnerability[3] in the Intel(R) PRO/1000  ethernet card driver that could allow a local attacker to read some  bytes of kernel memory.
 
 3. Sparse vulnerabilities (CAN-2004-0495[4])  
 
 Al Viro, by using Sparse[5] (a code inspection tool), found several  vulnerabilities which, in the worst case, might allow local attackers  to obtain root privileges.


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[6]. More detailed instructions are also available in Portuguese  at our Moin[7] page.
