Summary

Vulnerability in Codeready Linux Builder (CVE-2025-13601). Data can be tampered with by attackers.

Original description

The description as published by the source.

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.
