NewStart CGSL CORE 5.04 / MAIN 5.04 : openssl Multiple Vulnerabilities (NS-SA-2019-0206)
medium Nessus Plugin ID 129941
Language:
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:- The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i).
Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p).
(CVE-2018-0734)
- If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable non- stitched ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q). (CVE-2019-1559)
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.See Also
