NewStart CGSL CORE 5.04 / MAIN 5.04 : openssl Multiple Vulnerabilities (NS-SA-2019-0065)

Medium Nessus Plugin ID 127262

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has openssl packages installed that are affected by multiple vulnerabilities:

- While parsing an IPAddressFamily extension in an X.509 certificate, it is possible to do a one-byte overread.
This would result in an incorrect text display of the certificate. This bug has been present since 2006 and is present in all versions of OpenSSL before 1.0.2m and 1.1.0g. (CVE-2017-3735)

- Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
(CVE-2018-0495)

- OpenSSL RSA key generation was found to be vulnerable to cache side-channel attacks. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover parts of the private key. (CVE-2018-0737)

- Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g).
Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).
(CVE-2018-0739)

- A microprocessor side-channel vulnerability was found on SMT (e.g, Hyper-Threading) architectures. An attacker running a malicious process on the same core of the processor as the victim process can extract certain secret information. (CVE-2018-5407)

- During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o). (CVE-2018-0732)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL openssl packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
