Vulnerability Details

CVEID: CVE-2018-16396 DESCRIPTION: Ruby could allow a remote attacker to bypass security restrictions, caused by the failure to properly check security controls. By sending a specially crafted Array#pack and String#unpack array, an attacker could exploit this vulnerability to bypass security controls on the target system.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/153078&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID: CVE-2018-16395 DESCRIPTION: Ruby could allow a remote attacker to bypass security restrictions, caused by a flaw when comparing two OpenSSL::X509::Name objects using == in the OpenSSL library. By sending specially-crafted arguments, an attacker could exploit this vulnerability to to create an illegitimate certificate that may be accepted as legitimate.

CVEID: CVE-2018-14618 DESCRIPTION: cURL libcurl is vulnerable to a buffer overflow, caused by an integer overflow flaw in the Curl_ntlm_core_mk_nt_hash internal function in the NTLM authentication code. By sending an overly long password, a remote attacker could overflow a buffer and execute arbitrary code and cause the application to crash.
CVSS Base Score: 9.8

CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2018-16842 DESCRIPTION: cURL could allow a remote attacker to obtain sensitive information, caused by a heap-based buffer over-read in the display function in the command line tool. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service condition.
CVSS Base Score: 6.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/152300&gt; for the current score

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L)

CVEID: CVE-2018-16839 DESCRIPTION: cURL is vulnerable to a denial of service, caused by the incorrect verification of the passed-in lengths for the name and password fields by the Curl_auth_create_plain_message function. By sending a user name that exceeds 2 GB, an attacker could overflow a buffer and cause a denial of service.
CVSS Base Score: 5.3

CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2018-0737 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a cache-timing side channel attack in the RSA Key generation algorithm. An attacker with access to mount cache timing attacks during the RSA key generation process could exploit this vulnerability to recover the private key and obtain sensitive information.
CVSS Base Score: 3.3

CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-0735 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing side channel attack in the ECDSA signature algorithm. An attacker could exploit this vulnerability using variations in the signing algorithm to recover the private key.
CVSS Base Score: 3.7

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-0734 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a timing side channel attack in the DSA signature algorithm. An attacker could exploit this vulnerability using variations in the signing algorithm to recover the private key.
CVSS Base Score: 3.7

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-0732 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the sending of a very large prime value to the client by a malicious server during key agreement in a TLS handshake. By spending an unreasonably long period of time generating a key for this prime, a remote attacker could exploit this vulnerability to cause the client to hang.

CVEID: CVE-2018-5407 DESCRIPTION: Multiple SMT/Hyper-Threading architectures and processors could allow a local attacker to obtain sensitive information, caused by execution engine sharing on Simultaneous Multithreading (SMT) architecture. By using the PortSmash new side-channel attack, an attacker could run a malicious process next to legitimate processes using the architectures parallel thread running capabilities to leak encrypted data from the CPU’s internal processes. Note: This vulnerability is known as PortSmash.
