Vulnerability Details

CVEID: 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

CVEID: 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.
