CWEhttps://cwe.mitre.org/data/definitions/192.html

In xmlIO in libxml2 before 2.15.4, an inconsistency in xmlOutputWriteCallback and xmlBufUse causes negative lengths to reach write callbacks, aka a lack of a check for integer overflow before calling writecallback. This has security relevance for many types of uses of that length value within a callback.

Weakness

Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types.
