CVE-2025-13601

Glib: integer overflow in in g_escape_uri_string()

State: Published
Severity: 7.7 High
Published: Nov 26, 2025
Updated: Aug 31, 2026
Reserved: Nov 24, 2025

Description

A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
