NewStart CGSL MAIN 4.05 : gnutls Multiple Vulnerabilities (NS-SA-2019-0109)

High Nessus Plugin ID 127344

Synopsis

The remote machine is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 4.05, has gnutls packages installed that are affected by multiple vulnerabilities:

- Stack-based buffer overflow in the cdk_pk_get_keyid function in lib/opencdk/pubkey.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allows remote attackers to have unspecified impact via a crafted OpenPGP certificate.
(CVE-2017-5336)

- The stream reading functions in lib/opencdk/read- packet.c in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to cause a denial of service (out-of-memory error and crash) via a crafted OpenPGP certificate. (CVE-2017-5335)

- Multiple heap-based buffer overflows in the read_attribute function in GnuTLS before 3.3.26 and 3.5.x before 3.5.8 allow remote attackers to have unspecified impact via a crafted OpenPGP certificate.
(CVE-2017-5337)

- A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. (CVE-2016-8610)

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