CVE-2015-1819
GHSA-q7wx-62r7-j2x7 |
| Summary | Nokogiri gem contains several vulnerabilities in libxml2 and libxslt Several vulnerabilities were discovered in the libxml2 and libxslt libraries that the Nokogiri gem depends on. CVE-2015-1819 A denial of service flaw was found in the way libxml2 parsed XML documents. This flaw could cause an application that uses libxml2 to use an excessive amount of memory. CVE-2015-7941 libxml2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted specially XML data. CVE-2015-7942 The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data. CVE-2015-7995 The xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not check whether the parent node is an element, which allows attackers to cause a denial of service using a specially crafted XML document. CVE-2015-8035 The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data. Another vulnerability was discoverd in libxml2 that could cause parsing of unclosed comments to result in "conditional jump or move depends on uninitialized value(s)" and unsafe memory access. This issue does not have a CVE assigned yet. See related URLs for details. Patched in v1.6.7.rc4. |
