CVE-2014-2139

Cisco CVE-2014-2139 affects Cisco ONS 15454 Controller Cards running software 9.6 and earlier. The flaw allows an unauthenticated, remote attacker to trigger a FIN attack that exhausts file descriptors, preventing access to flash memory and causing a denial of service. The root cause is exhaustio...

Cisco ONS 15454 Controller Card Denial of Service Vulnerability

A vulnerability in the code of the Cisco ONS 15454 Controller Cards could allow an unauthenticated, remote attacker to cause the control card to reset. The vulnerability is due to improper instructions to reload the controller card. A CAL pipe fails to open when the file descriptors are exhausted...

Cisco ONS 15454 Controller Card Denial of Service Vulnerability

A vulnerability in the code of the Cisco ONS 15454 Controller Cards could allow an unauthenticated, remote attacker to prevent system access to the flash memory on the control card.
