 Mandriva Linux Security Advisory                         MDKSA-2007:195
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : kernel
 Date    : October 15, 2007
 Affected: 2007.0, 2007.1
 _______________________________________________________________________
 
 Problem Description:
 
 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 A stack-based buffer overflow in the random number generator could
 allow local root users to cause a denial of service or gain privileges
 by setting the default wakeup threshold to a value greater than the
 output pool size (CVE-2007-3105).
 
 The lcd_write function did not limit the amount of memory used by
 a caller, which allows local users to cause a denial of service
 (memory consumption) (CVE-2007-3513).
 
 The decode_choice function allowed remote attackers to cause a denial
 of service (crash) via an encoded out-of-range index value for a choice
 field which triggered a NULL pointer dereference (CVE-2007-3642).
 
 The Linux kernel allowed local users to send arbitrary signals
 to a child process that is running at higher privileges by
 causing a setuid-root parent process to die which delivered an
 attacker-controlled parent process death signal (PR_SET_PDEATHSIG)
 (CVE-2007-3848).
 
 The aac_cfg_openm and aac_compat_ioctl functions in the SCSI layer
 ioctl patch in aacraid did not check permissions for ioctls, which
 might allow local users to cause a denial of service or gain privileges
 (CVE-2007-4308).
 
 The IA32 system call emulation functionality, when running on the
 x86_64 architecture, did not zero extend the eax register after the
 32bit entry path to ptrace is used, which could allow local users to
 gain privileges by triggering an out-of-bounds access to the system
 call table using the %RAX register (CVE-2007-4573).
 
 In addition to these security fixes, other fixes have been included
 such as:
 
   - More NVidia PCI ids wre added
   - The 3w-9xxx module was updated to version 2.26.02.010
   - Fixed the map entry for ICH8
   - Added the TG3 5786 PCI id
   - Reduced the log verbosity of cx88-mpeg
