CVE-2025-13601

Severity CVSS v4.0:
Pending analysis
Type:
CWE-190 Integer Overflow or Wraparound
Publication date:
26/11/2025
Last modified:

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.
