Denial of Service loss of privacy .
:
IPsec protocol stack did not correctly handle fragmented ESP packets. A remote attacker could exploit this to crash the system, leading to a denial of service.(CVE-2007-6282)
The 64bit kernel did not correctly handle hrtimer updates. A local attacker could request a large expiration value and cause the system to hang, leading to a denial of service. (CVE-2007-6712)
The ia32 emulation under 64bit kernels did not fully clear uninitialized data. A local attacker could read private kernel memory, leading to a loss of privacy. (CVE-2008-0598)
A race condition was discovered between ptrace and utrace in the kernel. A
local attacker could exploit this to crash the system, leading to a denial
of service. (CVE-2008-2365)
The copy_to_user routine in the kernel did not correctly clear memory destination addresses when running on 64bit kernels. A local attacker could exploit this to gain access to sensitive kernel memory, leading to a loss of privacy. (CVE-2008-2729)
The PPP over L2TP routines in the kernel did not correctly handle certain messages. A remote attacker could send a specially crafted packet that could crash the system or execute arbitrary code. (CVE-2008-2750)
Gabriel Campana discovered that SCTP routines did not correctly check for large addresses. A local user could exploit this to allocate all available memory, leading to a denial of service. (CVE-2008-2826)
