CVE-2022-30045Public exploitNetwork attack vector

Application crash via entity-decoding boundary read

Published May 17, 2022 · Updated Aug 3, 2024

Heap out-of-bounds read in ezXML 0.8.6 allows attackers to crash an application when it parses a crafted XML file. After reallocating the entity-expansion buffer, ezxml_decode() calls strchr() from a pointer at the end of the new allocation. The application must parse attacker-controlled XML; the published proof of concept demonstrates a process crash.
