MEDIUM 6.5 Microsoft
CVE-2023-29469
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).
