Security Bulletin: IBM RackSwitch firmware products are affected by vulnerabilities in OpenSSL

Description

## Summary The following vulnerabilites in OpenSSL have been addressed by IBM RackSwitch firmware products. ## Vulnerability Details ** CVEID: **[CVE-2020-1971](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-1971>) ** DESCRIPTION: **OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference. If the GENERAL_NAME_cmp function contain an EDIPARTYNAME, an attacker could exploit this vulnerability to cause the application to crash. CVSS Base score: 7.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/192748](<https://exchange.xforce.ibmcloud.com/vulnerabilities/192748>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) ** CVEID: **[CVE-2021-23840](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23840>) ** DESCRIPTION: **OpenSSL is vulnerable to a denial of service, caused by an integer overflow in CipherUpdate. By sending an overly long argument, an attacker could exploit this vulnerability to cause the application to crash. CVSS Base score: 7.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/196848](<https://exchange.xforce.ibmcloud.com/vulnerabilities/196848>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) ** CVEID: **[CVE-2021-23841](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23841>) ** DESCRIPTION: **OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the X509_issuer_and_serial_hash() function. By parsing the issuer field, an attacker could exploit this vulnerability to cause the application to crash. CVSS Base score: 7.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/196847](<https://exchange.xforce.ibmcloud.com/vulnerabilities/196847>) for the current score. CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) ** CVEID: **[CVE-2021-3712](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3712>) ** DESCRIPTION: **OpenSSL could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read when processing ASN.1 strings. By sending specially crafted data, an attacker could exploit this vulnerability to read contents of memory on the system or perform a denial of service attack. CVSS Base score: 6.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/208073](<https://exchange.xforce.ibmcloud.com/vulnerabilities/208073>) for the current score.

Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin. ## 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. ## Document Location Worldwide [{"Business Unit":{"code":"BU050","label":"BU NOT IDENTIFIED"},"Product":{"code":"SSWLYD","label":"PureFlex System \u0026amp; Flex System"},"Component":"","Platform":[{"code":"PF009","label":"Firmware"}],"Version":"All","Edition":""}]
