   An update that fixes two vulnerabilities is now available.

Description:

   This update for glib2 fixes the following issues:

   - CVE-2021-27218: g_byte_array_new_take takes a gsize as length but stores
     in a guint, this patch will refuse if the length is larger than guint.
     (bsc#1182328)
   - CVE-2021-27219: g_memdup takes a guint as parameter and sometimes leads
     into an integer overflow, so add a g_memdup2 function which uses gsize
     to replace it. (bsc#1182362)
