6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Summary
An issue was discovered in ezXML 0.8.3 through 0.8.6. The function ezxml_decode, while parsing a crafted XML file, performs incorrect memory handling, leading to a heap-based buffer over-read while running strchr() starting with a pointer after a '\0' character (where the processing of a string was finished).
