Oracle VM VirtualBox < 5.0.22 Multiple Vulnerabilities (July 2016 CPU)

High Nessus Plugin ID 92458

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 5.0.22. It is, therefore, affected by multiple vulnerabilities in the bundled OpenSSL component :

- 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)

- Flaws exist in the aesni_cbc_hmac_sha1_cipher() function in file crypto/evp/e_aes_cbc_hmac_sha1.c and the aesni_cbc_hmac_sha256_cipher() function in file crypto/evp/e_aes_cbc_hmac_sha256.c that are triggered when the connection uses an AES-CBC cipher and AES-NI is supported by the server. A man-in-the-middle attacker can exploit these to conduct a padding oracle attack, resulting in the ability to decrypt the network traffic.
(CVE-2016-2107)

- Multiple unspecified flaws exist in the d2i BIO functions when reading ASN.1 data from a BIO due to invalid encoding causing a large allocation of memory.
An unauthenticated, remote attacker can exploit these to cause a denial of service condition through resource exhaustion. (CVE-2016-2109)

- An out-of-bounds read error exists in the X509_NAME_oneline() function within file crypto/x509/x509_obj.c when handling very long ASN1 strings. An unauthenticated, remote attacker can exploit this to disclose the contents of stack memory.
(CVE-2016-2176)

Solution

Upgrade to Oracle VM VirtualBox version 5.0.22 or later as referenced in the July 2016 Oracle Critical Patch Update advisory.
