Description:
Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious, local users and malicious people to cause a DoS (Denial of Service).
1) The "sys_perfmon()" function on Itanium (IA64) systems does not correctly handle file descriptor reference counts, which can be exploited to cause a DoS by consuming all available file descriptors.
2) The "clip_mkip()" function in net/atm/clip.c may dereference a previously freed pointer when processing received data, which can be exploited to cause a kernel panic.
Solution:
Update to version 2.6.18.
Provided and/or discovered by:
1) Reported by the vendor.
2) ADLab, Venustech info Ltd CHINA.
