Oracle VM VirtualBox < 4.3.36 / 5.0.18 Multiple Vulnerabilities (April 2016 CPU)

medium Nessus Plugin ID 90680

Synopsis

An application installed on the remote host is affected by multiple vulnerabilities.

Description

The Oracle VM VirtualBox application installed on the remote host is a version prior to 4.3.36 or 5.0.18. It is, therefore, affected by an unspecified flaw in the Core subcomponent that allows a local attacker to gain elevated privileges. Additionally, multiple vulnerabilities exist in the bundled version of OpenSSL :

- A flaw exists in the ssl3_get_key_exchange() function in file s3_clnt.c when handling a ServerKeyExchange message for an anonymous DH ciphersuite with the value of 'p' set to 0. A attacker can exploit this, by causing a segmentation fault, to crash an application linked against the library, resulting in a denial of service.
(CVE-2015-1794)

- A carry propagating flaw exists in the x86_64 Montgomery squaring implementation that may cause the BN_mod_exp() function to produce incorrect results. An attacker can exploit this to obtain sensitive information regarding private keys. (CVE-2015-3193)

- A NULL pointer dereference flaw exists in file rsa_ameth.c due to improper handling of ASN.1 signatures that are missing the PSS parameter. A remote attacker can exploit this to cause the signature verification routine to crash, resulting in a denial of service condition. (CVE-2015-3194)

- A flaw exists in the ASN1_TFLG_COMBINE implementation in file tasn_dec.c related to handling malformed X509_ATTRIBUTE structures. A remote attacker can exploit this to cause a memory leak by triggering a decoding failure in a PKCS#7 or CMS application, resulting in a denial of service. (CVE-2015-3195)

- A race condition exists in s3_clnt.c that is triggered when PSK identity hints are incorrectly updated in the parent SSL_CTX structure when they are received by a multi-threaded client. A remote attacker can exploit this, via a crafted ServerKeyExchange message, to cause a double-free memory error, resulting in a denial of service. (CVE-2015-3196)

- A cipher algorithm downgrade vulnerability exists due to a flaw that is triggered when handling cipher negotiation. A remote attacker can exploit this to negotiate SSLv2 ciphers and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled on the server. Note that this vulnerability only exists if the SSL_OP_NO_SSLv2 option has not been disabled.
(CVE-2015-3197)

Solution

Upgrade to Oracle VM VirtualBox version 4.3.36 / 5.0.18 or later as referenced in the April 2016 Oracle Critical Patch Update advisory.
