Vulnerability Details

CVE-ID: CVE-2019-6486
Description: Golang Go is vulnerable to a denial of service, caused by

CVEID: CVE-2018-16875
DESCRIPTION: Go Programming Language is vulnerable to a denial of service,
caused by the failure to limit the amount of work performed for each chain
verification. By sending specially-crafted pathological inputs, a remote
attacker could exploit this vulnerability to cause a denial of service
condition.

IBM Event Streams is affected by cURL vulnerabilities

Product:             WebSphere IBM Event Streams

Software version:    All Versions

Operating system(s): Linux

Reference #:         0876554

Security Bulletin

Summary

IBM Event Streams has addressed the following vulnerabilities in the shipped
cURL libraries.

Vulnerability Details

CVEID: CVE-2018-16890
DESCRIPTION: cURL libcurl could allow a remote attacker to obtain sensitive
information. The function handling incoming NTLM type-2 messages fails to
properly validate incoming data and triggers an integer overflow. An attacker
could exploit this vulnerability using the overflow to accept a bad length +
offset combination that would lead to a buffer read out-of-bounds.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
156649 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2019-3822
DESCRIPTION: cURL libcurl is vulnerable to a stack-based buffer overflow. The
function creating an outgoing NTLM type-3 header generates the request HTTP
header contents based on previously received data. By sending an overly large
"nt response" data, a remote attacker could overflow a buffer and execute
arbitrary code on the system.
CVSS Base Score: 7.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
156651 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2019-3823
DESCRIPTION: cURL libcurl could allow a remote attacker to obtain sensitive
information, caused by an out-of-bounds read when handling certain SMTP
responses. An attacker could exploit this vulnerability to obtain sensitive
information.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
156650 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
