CVE-2022-40303 (GCVE-0-2022-40303)

Vulnerability from cvelistv5 – Published: 2022-11-22 00:00 – Updated: 2025-04-29 04:24

Summary

An issue was discovered in libxml2 before 2.10.3. When parsing a multi-gigabyte XML document with the XML_PARSE_HUGE parser option enabled, several integer counters can overflow. This results in an attempt to access an array at a negative 2GB offset, typically leading to a segmentation fault.

Severity
