CVE-2021-42859:

A memory leak issue was discovered in Mini-XML v3.2 that could cause a denial of service.

CVE-2021-42860:

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 mxml_string_getc:2611.

"Fixed in master", but unsure about where the actual fix is.

Based on the Github issue, it should be fixed in 3.3. I was also not able to reproduce with current version 3.3 in tree.

I guess, we can close here and release _no_ GLSA.

Seeing https://github.com/michaelrsweet/mxml/issues/286, the CVE was rejected by upstream.

https://www.cve.org/CVERecord?id=CVE-2021-42859 also lists as disputed.
