Security Bulletin: Vulnerabilities in libxml2 affect IBM Flex System Chassis Management Module (CMM)

Description

## Summary IBM Chassis Management Module (CMM) has addressed the following vulnerabilities in libxml2. ## Vulnerability Details **Summary** IBM Chassis Management Module (CMM) has addressed the following vulnerabilities in libxml2. **Vulnerability Details:** **CVEID:** [CVE-2016-4658](<https://vulners.com/cve/CVE-2016-4658>) **Description:** The libxml2 library, as used in multiple products, could allow a remote attacker to execute arbitrary code on the system, caused by a memory corruption error. An attacker could exploit this vulnerability using a specially crafted XML document to execute arbitrary code on the system or cause a denial of service. CVSS Base Score: 9.8 CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/117175> 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) **CVEID:** [CVE-2016-9318](<https://vulners.com/cve/CVE-2016-9318>) **Description:** Libxml2 could allow a remote attacker to obtain sensitive information, caused by failure to offer a flag directly indicating the status of current document. By using a specially-crafted document to conduct a XML external entity (XXE) attack, an attacker could exploit this vulnerability to obtain sensitive information. CVSS Base Score: 5.5 CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/119018> for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) **CVEID:** [CVE-2016-9597](<https://vulners.com/cve/CVE-2016-9597>) **Description:** libxml2 is vulnerable to a denial of service, caused by a stack-based buffer overflow prior to detecting an invalid XML file. By persuading a victim to open a specially crafted XML file, a remote attacker could exploit this vulnerability to cause the application to crash. CVSS Base Score: 4.3 CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/121309> for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L) **Affected Products and Versions** Product | Affected Version ---|--- IBM Flex System Chassis Management Module (CMM) | 2PET **Remediation/Fixes:** Firmware fix versions are available on Fix Central: <http://www.ibm.com/support/fixcentral/>.
