| Package | Affected versions | Patched versions |
|---|---|---|
| nokogiri | < 1.8.5 | 1.8.5 |
| libxml2 | ≤ 2.9.8 |
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.
