Description:
A vulnerability has been reported in Cisco Intrusion Prevention System, which can be exploited by malicious people to cause a DoS (Denial of Service) or bypass certain security restrictions.
The vulnerability is caused due to an unspecified error in the processing of Jumbo Ethernet frames received on a Gigabit network interface and can be exploited to trigger a kernel panic.
Successful exploitation requires that the Gigabit network interface is configured for inline mode.
NOTE: On platforms that continue to forward network traffic after a kernel panic takes place, the vulnerability will result in the bypassing of configured access controls and detection rules.
The vulnerability is reported in versions prior to 5.1(8)E2 and 6.0(5)E2.
