Security Bulletin
Summary
Perl is vulnerable to buffer overflow issues. CVE-2020-10543: This vulnerability is identified in 32 bit, but watsonx.data is deployd in 64 bit platform. Hence watsonx.data is not affected. CVE-2020-10878, CVE-2020-12723: If user supplied string and it is used in a regex in our code, this will cause instruction injection if IBM watsonx.data is not upgraded.
Vulnerability Details
CVEID: CVE-2020-10543
DESCRIPTION: Perl is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the nested regular expression quantifiers. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/183203 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H)
CVEID: CVE-2020-10878
DESCRIPTION: Perl could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow related to the mishandling of a PL_regkind[OP(n)] == NOTHING situation. By using a specially-crafted regular expression, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.6
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/183204 for the current score.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
