Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The remote Cisco IOS device is missing a vendor-supplied security patch and has an IOS service configured to use TLS or SSL. It is, therefore, affected by the following vulnerabilities in the bundled OpenSSL library :

- A buffer overflow error exists related to invalid DTLS fragment handling that can lead to execution of arbitrary code. Note this issue only affects OpenSSL when used as a DTLS client or server. (CVE-2014-0195)

- An error exists related to DTLS handshake handling that could lead to denial of service attacks. Note that this issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An unspecified error exists that allows an attacker to cause usage of weak keying material leading to simplified man-in-the-middle attacks. (CVE-2014-0224)

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCup22590.
