- CVEs with nessus.description==The version of Juniper ScreenOS running on the remote host is 6.3.x prior to 6.3.0r23. It is, therefore, affected by multiple vulnerabilities in its bundled version of OpenSSL :
- A flaw exists in the SSLv2 implementation, specifically in the get_client_master_key() function within file s2_srvr.c, due to accepting a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher. A man-in-the-middle attacker can exploit this to determine the MASTER-KEY value and decrypt TLS ciphertext by leveraging a Bleichenbacher RSA padding oracle. (CVE-2016-0703)
- A flaw exists in the SSLv2 oracle protection mechanism, specifically in the get_client_master_key() function within file s2_srvr.c, due to incorrectly overwriting MASTER-KEY bytes during use of export cipher suites.
A remote attackers can exploit this to more easily decrypt TLS ciphertext by leveraging a Bleichenbacher RSA padding oracle. (CVE-2016-0704)
- A NULL pointer dereference flaw exists in the BN_hex2bn() and BN_dec2bn() functions. A remote attacker can exploit this to trigger a heap corruption, resulting in the execution of arbitrary code. (CVE-2016-0797)
- A flaw exists that allows a cross-protocol Bleichenbacher padding oracle attack known as DROWN (Decrypting RSA with Obsolete and Weakened eNcryption).
This vulnerability exists due to a flaw in the Secure Sockets Layer Version 2 (SSLv2) implementation, and it allows captured TLS traffic to be decrypted. A man-in-the-middle attacker can exploit this to decrypt the TSL connection by utilizing previously captured traffic and weak cryptography along with a series of specially crafted connections to an SSLv2 server that uses the same private key. (CVE-2016-0800)
- A heap buffer overflow condition exists in the EVP_EncodeUpdate() function within file crypto/evp/encode.c that is triggered when handling a large amount of input data. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-2105)
- A heap buffer overflow condition exists in the EVP_EncryptUpdate() function within file crypto/evp/evp_enc.c that is triggered when handling a large amount of input data after a previous call occurs to the same function with a partial block. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2016-2106)
- A remote code execution vulnerability exists in the ASN.1 encoder due to an underflow condition that occurs when attempting to encode the value zero represented as a negative integer. An unauthenticated, remote attacker can exploit this to corrupt memory, resulting in the execution of arbitrary code. (CVE-2016-2108)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number
