critical Nessus Plugin ID 187367

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.06, has gnutls packages installed that are affected by multiple vulnerabilities:

- An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure. (CVE-2020-24659)

- A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences. (CVE-2021-20231)

- A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences. (CVE-2021-20232)

- A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function. (CVE-2022-2509)

Note that Nessus has not tested for these issues 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.
