Details
Nokogiri 1.8.5 has been released. This is a security and bugfix release. It addresses two CVEs in upstream libxml2 rated as "medium" by Red Hat, for which details are below. If you're using your distro's system libraries, rather than Nokogiri's vendored libraries, there's no security need to upgrade at this time, though you may want to check with your distro whether they've patched this (Canonical has patched Ubuntu packages). Note that these patches are not yet (as of 2018-10-04) in an upstream release of libxml2. Full details about the security update are available in Github Issue #1785. [#1785]: https://github.com/sparklemotion/nokogiri/issues/1785 ----- [MRI] Pulled in upstream patches from libxml2 that address CVE-2018-14404 and CVE-2018-14567. Full details are available in #1785. Note that these patches are not yet (as of 2018-10-04) in an upstream release of libxml2. ----- CVE-2018-14404 Permalink: https://people.canonical.com/~ubuntu-security/cve/2018/CVE-2018-14404.html Description: A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application Canonical rates this vulnerability as "Priority: Medium" ----- CVE-2018-14567 Permalink: https://people.canonical.com/~ubuntu-security/cve/2018/CVE-2018-14567.html Description: infinite loop in LZMA decompression Canonical rates this vulnerability as "Priority: Medium"
