 Mandriva Linux Security Advisory                         MDKSA-2007:216
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : kernel
 Date    : November 13, 2007
 Affected: Corporate 3.0, Multi Network Firewall 2.0
 _______________________________________________________________________
 
 Problem Description:
 
 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 A typo in the Linux kernel caused RTA_MAX to be used as an array size
 instead of RTN_MAX, which lead to an out of bounds access by certain
 functions (CVE-2007-2172).
 
 The IPv6 protocol allowed remote attackers to cause a denial of
 service via crafted IPv6 type 0 route headers that create network
 amplification between two routers (CVE-2007-2242).
 
 The random number feature did not properly seed pools when there was
 no entropy, or used an incorrect cast when extracting entropy, which
 could cause the random number generator to provide the same values
 after reboots on systems without an entropy source (CVE-2007-2453).
 
 A memory leak in the PPPoE socket implementation allowed local users
 to cause a denial of service (memory consumption) by creating a
 socket using connect, and releasing it before the PPPIOCGCHAN ioctl
 is initialized (CVE-2007-2525).
 
 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 hugetlb_vmtruncate_list() and hugetlb_vmtruncate() functions in the
 Linux kernel perform certain pio_tree calculations using HPAGE_SIZE
 intead of PAGE_SIZE units, which may allow local users to cause a
 denial of service (panic) via unspecified vectors (CVE-2007-4133).
 
 To update your kernel, please follow the directions located at:
