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
