Description:
A vulnerability has been reported in Cisco IOS, which potentially can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to an error in validating whether certain system memory has been corrupted by a heap-based buffer overflow before the internal operating system timers execute code from the affected memory area. This can potentially be exploited to execute arbitrary code in conjunction with some other heap-based buffer overflow vulnerability.
The vulnerability has been reported to affect all Cisco products that run Cisco IOS Software.
Note: The vendor has reported that the vulnerability was fixed as a result of continued research related to the demonstration of an exploit for the IPv6 vulnerability.
