| Detailed Description |
According to its banner, the remote web server uses a version of OpenSSL 0.9.8 prior to 0.9.8zc. The OpenSSL library is, therefore, affected by the following vulnerabilities :
- An error exists related to the way SSL 3.0 handles padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. A man-in-the-middle attacker can decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. This is also known as the 'POODLE' issue. (CVE-2014-3566)
- An error exists related to session ticket handling that can allow denial of service attacks via memory leaks. (CVE-2014-3567)
- An error exists related to the build configuration process and the 'no-ssl3' build option that allows servers and clients to process insecure SSL 3.0 handshake messages. (CVE-2014-3568)
* Note: This check solely relied on the banner of the remote Web server to assess this vulnerability, so this might be a false positive.
