Author: joneum Date: Thu Jul 23 18:36:06 2020 New Revision: 542952 URL: https://svnweb.freebsd.org/changeset/ports/542952 Log: MFH: r542951 SECURITY UPDATE: Buffer overflow Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels, assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass invalid utf-8 strings to functions like pango_itemize.
