Resolved Caveats
Successful repeated exploitation of any of these vulnerabilities may lead to a sustained
Denial-of-Service (DoS); however, vulnerabilities are not known to compromise either the
confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow
an attacker will not be able to decrypt any previously encrypted information.
The vulnerable cryptographic library is used in the following Cisco products:
– Cisco IOS, documented as Cisco bug ID CSCsd85587
– Cisco IOS XR, documented as Cisco bug ID CSCsg41084
– Cisco PIX and ASA Security Appliances, documented as Cisco bug ID CSCse91999
– Cisco Unified CallManager, documented as Cisco bug ID CSCsg44348
– Cisco Firewall Service Module (FWSM)
This vulnerability is also being tracked by CERT/CC as VU#754281.

Cisco IOS device may crash while processing malformed Secure Sockets Layer (SSL) packets. In
order to trigger these vulnerabilities, a malicious client must send malformed packets during the SSL
protocol exchange with the vulnerable device.
