CVE-2023-29469 (GCVE-0-2023-29469)

Vulnerability from cvelistv5 – Published: 2023-04-24 00:00 – Updated: 2025-02-04 21:02

Summary

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).

Severity

6.5 (Medium)
