Vulnerability Details
DESCRIPTION: libexpat is vulnerable to a denial of service, caused by improper input validation in xmltok_impl.c. By persuading a victim to open a specially-crafted content with malformed encoding, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 3.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/219782 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2021-35940
DESCRIPTION: Apache Portable Runtime could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds array read in the apr_time_exp*() functions. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, or cause a denial of service condition.
CVSS Base score: 9.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/207999 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H)
CVEID: CVE-2011-0419
DESCRIPTION: Apache Portable Runtime (APR) is vulnerable to a denial of service, caused by an error in the apr_fnmatch() function when processing specific patterns with the "*" wildcard. A remote attacker could exploit this vulnerability to consume all available CPU and memory resources resulting in a denial of service.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/67414 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2009-3720
DESCRIPTION: The Expat XML Parser is vulnerable to a denial of service, caused by an error when parsing UTF-8 sequences. A remote attacker could exploit this vulnerability to cause the application using the affected library to crash.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/52686 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2009-3560
DESCRIPTION: Expat is vulnerable to a denial of service, caused by the improper handling of XML data by the big2_toUtf8 function within the libexpat library. A remote attacker could exploit this vulnerability using a specially-crafted XML document containing malformed UTF-8 sequences that trigger a buffer over-read to cause the application to crash.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/54598 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2012-0840
DESCRIPTION: Apache APR is vulnerable to a denial of service, caused by insufficient randomization of hash data structures. By sending multiple specially-crafted HTTP POST requests to an affected application containing conflicting hash key values, a remote attacker could exploit this vulnerability to cause the consumption of CPU resources.
CVSS Base score: 5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/73096 for the current score.
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2022-28331
DESCRIPTION: Apache Portable Runtime (APR) could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the apr_socket_sendv() function. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246065 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID: CVE-2017-12618
DESCRIPTION: Apache Portable Runtime Utility (APR-util)is vulnerable to a denial of service, caused by failing to validate the integrity of SDBM database files used by apr_sdbm*() functions. By making a specially-crafted program or process, a local authenticated attacker could exploit this vulnerability to cause the application to crash.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/134048 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2022-25147
DESCRIPTION: Apache Portable Runtime (APR) could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the apr_base64 functions. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/246064 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L)
CVEID: CVE-2023-50304
DESCRIPTION: IBM DOORS Web Access is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.

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.
