| CVE-2009-3720 | 0.02 | — | 0.28 | Nov 3, 2009 | The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that… | |||
| CVE-2019-15903 | Hig | 0.01 | 7.5 | 0.07 | Sep 4, 2019 | In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. | ||
