Description: | Summary: The remote host is missing an update for the Huawei EulerOS 'expat' package(s) announced via the EulerOS-SA-2019-2063 advisory.
Vulnerability Insight: In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks).(CVE-2018-20843)
( Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.(CVE-2015-1283)
The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716.(CVE-2016-4472)
The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876.(CVE-2016-5300)
Affected Software/OS: 'expat' package(s) on Huawei EulerOS V2.0SP3.
Solution: Please install the updated package(s).
CVSS Score: 7.8
CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
