According to the versions of the libxslt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
The xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not check if the parent node is an element, which allows attackers to cause a denial of service via a crafted XML file, related to a βtype confusionβ issue.(CVE-2015-7995)
numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles namespace nodes, which allows remote attackers to cause a denial of service (out-of-bounds heap memory access) or possibly have unspecified other impact via a crafted document.(CVE-2016-1683)
numbers.c in libxslt before 1.1.29, as used in Google Chrome before 51.0.2704.63, mishandles the i format token for xsl:number data, which allows remote attackers to cause a denial of service (integer overflow or resource consumption) or possibly have unspecified other impact via a crafted document.(CVE-2016-1684)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
