GHSA-7jv7-hr35-fwjr PUBLISHED CVSS 6.5 MEDIUM

Record from GitHub Advisory Database · Published April 24, 2023

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).
