Description
An issue was discovered in libxml2 before 2.10.4. When hashing empty dict strings in a crafted XML document, xmlDictComputeFastKey in dict.c can produce non-deterministic values, leading to various logic and memory errors, such as a double free. This behavior occurs because there is an attempt to use the first byte of an empty string, and any value is possible (not solely the '\0' value).
A flaw was found in libxml2. This issue occurs when hashing empty strings which aren't null-terminated, xmlDictComputeFastKey could produce inconsistent results, which may lead to various logic or memory errors, including double free errors.
