"Evan Teran discovered that the Linux kernel ptrace routines did not
correctly handle certain requests robustly. Local attackers could
exploit this to crash the system, causing a denial of service.
(CVE-2007-3731)

It was discovered that hugetlb kernels on PowerPC systems did not
prevent the stack from colliding with reserved kernel memory. Local
attackers could exploit this and crash the system, causing a denial of
service. (CVE-2007-3739)

It was discovered that certain CIFS filesystem actions did not honor
the umask of a process. Local attackers could exploit this to gain
additional privileges. (CVE-2007-3740)

Wojciech Purczynski discovered that the Linux kernel ia32 syscall
emulation in x86_64 kernels did not correctly clear the high bits of
registers. Local attackers could exploit this to gain root privileges.
(CVE-2007-4573).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
