Summary

Multiple vulnerabilities in open source libraries affect IBM Db2 Federated.

Vulnerability Details

CVEID: CVE-2023-1370
DESCRIPTION: netplex json-smart-v2 is vulnerable to a denial of service, caused
by not limiting the nesting of arrays or objects. By sending a specially
crafted input, a remote attacker could exploit this vulnerability to cause a
stack exhaustion and crash the software.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
249885 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-2022-3171
DESCRIPTION: protobuf-java core and lite are vulnerable to a denial of service,
caused by a flaw in the parsing procedure for binary and text format data. By
sending non-repeated embedded messages with repeated or unknown fields, a
remote authenticated attacker could exploit this vulnerability to cause long
garbage collection pauses.
CVSS Base score: 5.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
238394 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2022-3509
DESCRIPTION: protobuf-java core and lite are vulnerable to a denial of service,
caused by a flaw in the parsing procedure for textformat data. By sending
non-repeated embedded messages with repeated or unknown fields, a remote
authenticated attacker could exploit this vulnerability to cause long garbage
collection pauses.
CVSS Base score: 5.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
239915 for the current score.
CVSS Vector: (CVSS:3.0/AV:A/AC:L/PR:L/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-2023-34462
DESCRIPTION: Netty is vulnerable to a denial of service, caused by a flaw with
allocating up to 16MB of heap for each channel during the TLS handshake the
SniHandler class. By sending a specially crafted client hello packet, a remote
authenticated attacker could exploit this vulnerability to cause a
OutOfMemoryError and so result in a denial of service condition.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
258713 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2023-32731
DESCRIPTION: gRPC could allow a remote attacker to obtain sensitive
information, caused by a flaw when gRPC HTTP2 stack raised a header size
exceeded error. By sending a specially crafted request, 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: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
257688 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H)

CVEID: CVE-2022-3510
DESCRIPTION: protobuf-java core and lite are vulnerable to a denial of service,
caused by a flaw in the parsing procedure for Message-Type Extensions. By
sending non-repeated embedded messages with repeated or unknown fields, a
remote authenticated attacker could exploit this vulnerability to cause long
garbage collection pauses.

IBM does not disclose key Db2 functionality nor replication steps for a
vulnerability to avoid providing too much information to any potential
malicious attacker. IBM does not want to enable a malicious attacker with
sufficient knowledge to craft an exploit of the vulnerability.

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.
