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 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.
