Description :

Doug Chapman discovered a flaw in the reference counting in the
sys_mq_open() function. By calling this function in a special way, a
local attacker could exploit this to cause a kernel crash.

Karl Janmar discovered that the /proc file system module used signed
data types in a wrong way. A local attacker could exploit this to read
random kernel memory, which could possibly contain sensitive data like
passwords or private keys. (CVE-2005-4605)

Yi Yang discovered an off-by-one buffer overflow in the sysctl()
system call. By calling sysctl with a specially crafted long string, a
local attacker could exploit this to crash the kernel or possibly even
execute arbitrary code with full kernel rights. (CVE-2005-4618)

Perceval Anichini found a buffer overflow in the TwinHan DST
Frontend/Card DVB driver. A local user could exploit this to crash the
kernel or possibly execute arbitrary code with full kernel rights.
This only affects Ubuntu 5.10. (CVE-2005-4639)

Stefan Rompf discovered that the
