Vulnerability Details
Summary
Three vulnerabilities in libxml2 were disclosed in December 2014. The IBM System Networking Switch products listed below have addressed the vulnerabilities.
Vulnerability Details:
CVE-ID: CVE-2014-0191
Description: Libxml2 is vulnerable to a denial of service, caused by the expansion of internal entities within the xmlParserHandlePEReference() function. A remote attacker could exploit this vulnerability using a specially-crafted XML document containing malicious attributes to consume all available CPU resources.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/93092> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2013-2877
Description: Google Chrome is vulnerable to a denial of service, caused by an out-of-bounds read in XML parsing. By persuading a victim to visit a specially-crafted Web site, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/85531> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
CVE-ID: CVE-2014-3660
Description: Libxml2 is vulnerable to a denial of service, caused by the expansion of recursive entities. A remote attacker could exploit this vulnerability using a specially-crafted XML document processed by an application using libxml2 to consume all available CPU resources.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/97656> for current score
CVSS Environmental Score*: Undefined
