Description :

The sys_mbind() function did not properly verify the validity of the
'maxnod' argument. A local user could exploit this to trigger a buffer
overflow, which caused a kernel crash. (CVE-2006-0557)

The SELinux module did not correctly handle the tracer SID when a
process was already being traced. A local attacker could exploit this
to cause a kernel crash. (CVE-2006-1052)

Al Viro discovered a local Denial of Service in the sysfs write buffer
handling. By writing a block with a length exactly equal to the
processor's page size to any writable file in /sys, a local attacker
could cause a kernel crash. (CVE-2006-1055)

John Blackwood discovered a race condition with single-step debugging
multiple processes at the same time. A local attacker could exploit
this to crash the system. This only affects the amd64 platform.
(CVE-2006-1066)

Marco Ivaldi discovered a flaw in the handling of the ID number of IP
packets. This number was incremented after receiving unsolicited TCP
SYN-ACK packets. A remote attacker coul
