Description


Some vulnerabilities have been reported in the Linux Kernel, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) A vulnerability is caused due to an error in the "e1000_clean_rx_irq()" function in drivers/net/e1000/e1000_main.c. This can be exploited to cause a kernel panic via specially crafted network packets sent to an affected system.

2) A vulnerability is caused due to an error within the RTL8169 driver when receiving overly large network packets. This can be exploited to cause a kernel panic via specially crafted network packets sent to an affected system.

3) A vulnerability is caused due to an error in the "e1000_clean_rx_irq()" function in drivers/net/e1000e/netdev.c. This can be exploited to cause a kernel panic via specially crafted network packets sent to an affected system.


Solution:
Update to version 2.6.32.8.

Provided and/or discovered by:
1) Neil Horman
