VMware ESXi Multiple OpenSSL Vulnerabilities (VMSA-2014-0006)
medium Nessus Plugin ID 87678

Synopsis
The remote VMware ESXi host is missing a security-related patch.Description
The remote VMware ESXi host is affected by multiple vulnerabilities in the OpenSSL third-party library :- A use-after-free error exists in the ssl3_read_bytes() function in file ssl/s3_pkt.c that is triggered when a second read is done to the function by multiple threads when SSL_MODE_RELEASE_BUFFERS is enabled. A man-in-the-middle attacker can exploit this to dereference already freed memory and inject arbitrary data into the SSL stream. (CVE-2010-5298)
- A NULL pointer dereference flaw exists in the do_ssl3_write() function in file ssl/s3_pkt.c due to a failure to properly manage a buffer pointer during certain recursive calls when SSL_MODE_RELEASE_BUFFERS is enabled. A remote attacker can exploit this, by triggering an alert condition, to cause a denial of service. (CVE-2014-0198)
- A flaw exists due to a failure to properly restrict processing of ChangeCipherSpec messages. A man-in-the-middle attacker can exploit this, via a crafted TLS handshake, to force the use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, resulting in the session being hijacked and sensitive information being disclosed. (CVE-2014-0224)
- A NULL pointer dereference flaw exists in the ssl3_send_client_key_exchange() function in file s3_clnt.c, when an anonymous ECDH cipher suite is used, that allows a remote attacker to cause a denial of service. (CVE-2014-3470)
Solution
Apply the appropriate patch according to the vendor advisory that pertains to ESXi version 5.0 / 5.1 / 5.5.See Also
