Security Bulletin: Multiple Security Issues in IBM Tealeaf Customer Experience on Cloud Network Capture Add-On

Security Bulletin


Summary

Multiple vulnerabilities in Apache HTTPD can cause denial of service and allow a remote attacker to bypass security restrictions and obtain sensitive information in IBM Tealeaf Customer Experience on Cloud Network Capture Add-On.
A Vulnerability in the Memcached library used by the IBM Tealeaf Customer Experience on Cloud Network Capture Add-On could permit a denial of service attack.
A Vulnerability in the OpenSSL library used by the IBM Tealeaf Customer Experience on Cloud Network Capture Add-On could permit a a remote attacker to obtain sensitive information.

Vulnerability Details

CVEID: CVE-2017-7679
DESCRIPTION: Apache HTTPD could allow a remote attacker to obtain sensitive information, caused by a buffer overread in mod_mime. By sending a specially crafted Content-Type response header, a remote attacker could exploit this vulnerability to read one byte past the end of a buffer.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/127420 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-2017-7668
DESCRIPTION: Apache HTTPD is vulnerable to a denial of service, caused by a buffer overread in the ap_find_token() function. By sending a specially crafted sequence of request headers, a remote attacker could exploit this vulnerability to cause a segmentation fault.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/127419 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:N/A:L)

CVEID: CVE-2017-3169
DESCRIPTION: Apache HTTPD is vulnerable to a denial of service, caused by a NULL pointer dereference in mod_ssl. By sending a specially crafted HTTP request to an HTTPS port, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/127417 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:N/A:L)

CVEID: CVE-2017-9951
DESCRIPTION: Memcached is vulnerable to a denial of service, caused by a heap-based buffer over-read in the try_read_command function. By sending a request to add/set a key, a remote attacker could exploit this vulnerability to cause a segmentation fault.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/128607 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:N/A:L)

CVEID: CVE-2017-3735
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error while parsing an IPAdressFamily extension in an X.509 certificate. An attacker could exploit this vulnerability to trigger an out-of-bounds read, resulting in an incorrect text display of the certificate.
