Security Bulletin


Summary

The product includes vulnerable components (e.g., framework libraries) that may be identified and exploited with automated tools. This update addresses these CVEs.

Vulnerability Details

CVEID:   CVE-2023-35116
DESCRIPTION:   Fasterxml jackson-databind is vulnerable to a denial of service, caused by a stack-based overflow. By persuading a victim to open a specially crafted content, a remote attacker could exploit this vulnerability to cause a denial of service. Note: The vendor disputes the vulnerability because the steps of constructing a cyclic data structure and trying to serialize it cannot be achieved by an external attacker.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258157 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID:   CVE-2023-34453
DESCRIPTION:   snappy-java is vulnerable to a denial of service, caused by an integer overflow in the shuffle function. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258186 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:   CVE-2023-34455
DESCRIPTION:   snappy-java is vulnerable to a denial of service, caused by the use of an unchecked chunk length in the hasNextChunk function. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258190 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-2023-34454
DESCRIPTION:   snappy-java is vulnerable to a denial of service, caused by an integer overflow in the compress function. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258188 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-2023-43642
DESCRIPTION:   snappy-java is vulnerable to a denial of service, caused by missing upper bound check on chunk length. By sending a specially crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/267079 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-2023-2976
DESCRIPTION:   Google Guava could allow a local authenticated attacker to obtain sensitive information, caused by a flaw with using Java's default temporary directory for file creation in FileBackedOutputStream. By sending a specially crafted request, an attacker could exploit this vulnerability to access the files in the default Java temporary directory, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258199 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:   CVE-2023-33201
DESCRIPTION:   The Bouncy Castle Crypto Package For Java (bc-java) could allow a remote attacker to obtain sensitive information, caused by not validating the X.500 name of any certificate in the implementation of the X509LDAPCertStoreSpi.java class. By using blind LDAP injection attack techniques, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/258653 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.
