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

critical Nessus Plugin ID 127344

Language:

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.

Upgrade the vulnerable CGSL gnutls packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
