OpenSSL 1.0.0 < 1.0.0m Multiple Vulnerabilities

high Nessus Plugin ID 73403

Synopsis

The remote service is affected by multiple vulnerabilities.

Description

According to its banner, the remote web server uses a version of OpenSSL 1.0.0 prior to 1.0.0m. The OpenSSL library is, therefore, reportedly affected by the following vulnerabilities :

- An error exists in the function 'ssl3_read_bytes' that could allow data to be injected into other sessions or allow denial of service attacks. Note this issue is only exploitable if 'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2010-5298)

- An error exists related to the implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) that could allow nonce disclosure via the 'FLUSH+RELOAD' cache side-channel attack. (CVE-2014-0076)

- A buffer overflow error exists related to invalid DTLS fragment handling that could lead to execution of arbitrary code. Note this issue only affects OpenSSL when used as a DTLS client or server. (CVE-2014-0195)

- An error exists in the function 'do_ssl3_write' that could allow a NULL pointer to be dereferenced leading to denial of service attacks. Note this issue is exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2014-0198)

- An error exists related to DTLS handshake handling that could lead to denial of service attacks. Note this issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An unspecified error exists that could allow an attacker to cause usage of weak keying material leading to simplified man-in-the-middle attacks.
(CVE-2014-0224)

- An unspecified error exists related to anonymous ECDH ciphersuites that could allow denial of service attacks. Note this issue only affects OpenSSL TLS clients. (CVE-2014-3470)

- An integer underflow condition exists in the EVP_DecodeUpdate() function due to improper validation of base64 encoded input when decoding. This allows a remote attacker, using maliciously crafted base64 data, to cause a segmentation fault or memory corruption, resulting in a denial of service or possibly the execution of arbitrary code. (CVE-2015-0292)

Solution

Upgrade to OpenSSL 1.0.0m or later.
