Description

## Summary Intel® Manycore Platform Software Stack (Intel® MPSS) for Linux and Windows have addressed the following vulnerabilities in libxml2. ## Vulnerability Details **Summary** Intel® Manycore Platform Software Stack (Intel® MPSS) for Linux and Windows have addressed the following vulnerabilities in libxml2. **Vulnerability Details** **CVEID:** [CVE-2017-16931](<https://vulners.com/cve/CVE-2017-16931>) **Description:** Xmlsoft libxml2 is vulnerable to a buffer overflow, caused by improper handling of parameter-entity references in xmlParserHandlePEReference function. By using a percent character in a DTD name, a remote attacker could overflow a buffer and execute arbitrary code on the system. CVSS Base Score: 7.3 CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/135488> for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L) **CVEID:** [CVE-2017-16932](<https://vulners.com/cve/CVE-2017-16932>) **Description:** Xmlsoft libxml2 is vulnerable to a denial of service, caused by an infinite recursion issue in parameter entities. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to exhaust available memory on the system. CVSS Base Score: 7.5 CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/135489> 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:H) **Affected Products and Versions** The following products used with Intel Xeon Phi PCI-Express cards (Intel Xeon Phi 3120A, Intel Xeon Phi 5110P, Intel Xeon Phi 7120A, and Intel Xeon Phi 7210P) on the System x systems: * iDataPlex dx360 M4 * NeXtScale nx360 M4 * PureFlex x220 M4 / x240 M4 / x240 M5 * x3850 X6 / x3950 X6 Product | Affected Version ---|--- Intel® Manycore Platform Software Stack (MPSS) for Linux & Windows | 3.8 **Remediation/Fixes** IBM recommends that you update the affected versions of Intel MPSS that are used with the Intel Xeon Phi cards supported in IBM System x Servers to MPSS version 3.8.4 or later.
