Vulnerability Details

CVEID: CVE-2024-21907
DESCRIPTION: Newtonsoft.Json before version 13.0.1 is affected by a mishandling of exceptional conditions vulnerability. Crafted data that is passed to the JsonConvert.DeserializeObject method may trigger a StackOverflow exception resulting in denial of service. Depending on the usage of the library, an unauthenticated and remote attacker may be able to cause the denial of service condition.
CWE: CWE-755: Improper Handling of Exceptional Conditions
CVSS Source: NVD
CVSS Base score: 7.5
CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2023-39017
DESCRIPTION: Quartz Job Scheduler could allow a remote attacker to execute arbitrary code on the system, caused by improper neutralization of user supplied-input by the org.quartz.jobs.ee.jms.SendQueueMessageJob.execute component. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CWE: CWE-94: Improper Control of Generation of Code ('Code Injection')
CVSS Source: IBM X-Force
CVSS Base score: 9.8
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2024-40642
DESCRIPTION: Netty netty-incubator-codec-ohttp could allow a remote attacker to bypass security restrictions, caused by improper validation of input values. By sending a specially crafted request, an attacker could exploit this vulnerability to gain complete control over the HTTP requests constructed from the parsed output.
CWE: CWE-20: Improper Input Validation
CVSS Source: IBM X-Force
CVSS Base score: 8.1
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2015-2325
DESCRIPTION: PCRE is vulnerable to a heap-based buffer overflow, caused by the improper bounds checking by the compile_branch() function. By using a specially-crafted regular expression, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CWE: CWE-125: Out-of-bounds Read
CVSS Source: IBM X-Force
CVSS Base score: 7.3
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

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.
