NewStart CGSL CORE 5.04 / MAIN 5.04 : gnutls Multiple Vulnerabilities (NS-SA-2019-0068)
Medium Nessus Plugin ID 127268
Synopsis
The remote machine is affected by multiple vulnerabilities.
Description
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has gnutls packages installed that are affected by multiple vulnerabilities:
- It was found that GnuTLS's implementation of HMAC- SHA-256 was vulnerable to Lucky Thirteen-style attack. A remote attacker could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. (CVE-2018-10844)
- It was found that GnuTLS's implementation of HMAC- SHA-384 was vulnerable to a Lucky Thirteen-style attack.
A remote attacker could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets. (CVE-2018-10845)
- A cache-based side channel attack was found in the way GnuTLS implements CBC-mode cipher suites. An attacker could use a combination of Just in Time Prime+probe and Lucky-13 attacks to recover plain text in a cross-VM attack scenario. (CVE-2018-10846)
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 gnutls packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
