## Description:

This update for glib2 fixes the following issues:

  * CVE-2025-14512: integer overflow in the GIO `escape_byte_string()` function
    when processing malicious files or remote filesystem attribute values can
    lead to denial-of-service (bsc#1254878).

    and `string_parse()` functions when processing attacker-influenced data may
    lead to crash or code execution (bsc#1254662).
  * CVE-2025-13601: heap-based buffer overflow in the `g_escape_uri_string()`
    function when processing strings with a large number of unacceptable
    characters may lead to crash or code execution (bsc#1254297).
