Resolved Caveats Caveats Resolved in Cisco IOS Release 12.2(37)SE These caveats are resolved in Cisco IOS Release 12.2.(37)SE: • CSCsb12598 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. 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. Cisco IOS is affected by the following vulnerabilities: - Processing ClientHello messages, documented as Cisco bug ID CSCsb12598 - Processing ChangeCipherSpec messages, documented as Cisco bug ID CSCsb40304 - Processing Finished messages, documented as Cisco bug ID CSCsd92405 Cisco has made free software available to address these vulnerabilities for affected customers. There are workarounds available to mitigate the effects of these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20070522-SSL.shtml.
