Name of the Vulnerable Software and Affected Versions Mini-XML version 3.2

Description A stack buffer overflow exists in Mini-XML. When inputting an unformed XML string to the "mxmlLoadString" API, it will cause a stack-buffer-overflow in mxml string getc. Note that it is unclear whether this input is allowed by the API specification.

Recommendations For Mini-XML version 3.2, as a temporary workaround, consider restricting the input to the mxmlLoadString API to prevent unformed XML strings until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.
