The mxmlwritenode function in mxml-file.c in mxml 2.9, 2.7, and possibly earlier allows remote attackers to cause a denial of service (stack consumption) via crafted xml file.

The mxmlDelete function in mxml-node.c in mxml 2.9, 2.7, and possibly earlier allows remote attackers to cause a denial of service (stack consumption) via crafted xml file.

An issue has been found in Mini-XML (aka mxml) 2.12. It is a stack-based buffer overflow in mxmlwritenode in mxml-file.c via vectors involving a double-precision floating point number and the '<order type="real">' substring, as demonstrated by testmxml.

DISPUTED A stack buffer overflow exists in Mini-XML v3.2. When inputting an unformed XML string to the mxmlLoadString API, it will cause a stack-buffer-overflow in mxmlstringgetc:2611. NOTE: it is unclear whether this input is allowed by the API specification.

DISPUTED A memory leak issue was discovered in Mini-XML v3.2 that could cause a denial of service. NOTE: testing reports are inconsistent, with some testers seeing the issue in both the 3.2 release and in the October 2021 development code, but others not seeing the issue in the 3.2 release.
