Security Bulletin: Multiple denial of service vulnerabilities with Expat may affect IBM HTTP Server shipped with IBM Service Delivery Manager (CVE-2012-0876, CVE-2012-1148, CVE-2016-4472 and CVE-2016-0718)

Description

## Summary IBM HTTP Server is shipped as components of IBM Service Delivery Manager. Information about a security vulnerability affecting IBM HTTP Server has been published in a security bulletin. ## Vulnerability Details **CVEID:** [_CVE-2012-0876_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-0876>)** DESCRIPTION:** Expat 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/73868_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/73868>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) **CVEID:** [_CVE-2012-1148_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-1148>)** DESCRIPTION:** Expat is vulnerable to a denial of service, caused by a memory leak in poolGrow when handling XML data. A remote attacker could exploit this vulnerability to cause the application using the vulnerable XML parsing library to crash. CVSS Base Score: 5 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/73867_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/73867>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) **CVEID:** [_CVE-2016-4472_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-4472>)** DESCRIPTION:** Expat XML parser is vulnerable to a denial of service, caused by the removal by compilers with certain optimization settings. By using a specially-crafted XML data, a remote attacker could exploit this vulnerability to cause the application to crash. CVSS Base Score: 5.3 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/114683_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/114683>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) **CVEID:** [_CVE-2016-0718_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0718>)** DESCRIPTION:** Expat is vulnerable to a buffer overflow, caused by improper bounds checking when processing malformed XML data. By using the Expat library, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the victim or cause the application to crash. CVSS Base Score: 9.8 CVSS Temporal Score: See [_https://exchange.xforce.ibmcloud.com/vulnerabilities/113408_](<https://exchange.xforce.ibmcloud.com/vulnerabilities/113408>) for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) ## Affected Products and Versions **Principal Product and Version(s)** | **Affected Supporting Product and Version** ---|--- IBM Service Delivery Manager version 7.2.1 through 7.2.4| IBM HTTP Server version 7.0.0.0 through 7.0.0.41 ## Remediation/Fixes **Principal Product and Version(s)** | **Affected Supporting Product and Version**| **Affected Supporting Product Security Bulletin** ---|---|--- IBM Service Delivery Manager version 7.2.1 through 7.2.4| IBM HTTP Server version 7.0.0.0 through 7.0.0.41| Consult the security bulletin [_Multiple Denial of Service vulnerabilities with Expat may affect IBM HTTP Server_](<http://www-01.ibm.com/support/docview.wss?uid=swg21988026>) for fix information. ## Workarounds and Mitigations None ## Get Notified about Future Security Bulletins Subscribe to [My Notifications](< http://www-01.ibm.com/software/support/einfo.html>) to be notified of important product support alerts like this. ### References [Complete CVSS v2 Guide](<http://www.first.org/cvss/v2/guide> "Link resides outside of ibm.com" ) [On-line Calculator v2](<http://nvd.nist.gov/CVSS-v2-Calculator> "Link resides outside of ibm.com" ) [Complete CVSS v3 Guide](<http://www.first.org/cvss/user-guide> "Link resides outside of ibm.com" ) [On-line Calculator v3](<http://www.first.org/cvss/calculator/3.0> "Link resides outside of ibm.com" ) Off ## Related Information [IBM Secure Engineering Web Portal](<http://www.ibm.com/security/secure-engineering/bulletins.html>) [IBM Product Security Incident Response Blog](<http://www.ibm.com/blogs/psirt>) ## Change History 18 October 2016: Original copy published *The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS 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."

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. ## Internal Use Only CVE-2012-0876, CVE-2012-1148, CVE-2016-4472 and CVE-2016-0718 [{"Product":{"code":"SSBH2C","label":"IBM Service Delivery Manager"},"Business Unit":{"code":"BU053","label":"Cloud & Data Platform"},"Component":"Security","Platform":[{"code":"PF002","label":"AIX"},{"code":"PF016","label":"Linux"},{"code":"PF033","label":"Windows"}],"Version":"7.2.1;7.2.2;7.2.3;7.2.4","Edition":"All Editions","Line of Business":{"code":"LOB45","label":"Automation"}}]
