    Summary: Updated xrdp packages fix security vulnerability

    Details: The updated packages fix a security vulnerability Access to the font glyphs in xrdp_painter.c is not bounds-checked. Since some of this data is controllable by the user, this can result in an out-of-bounds read within the xrdp executable. The vulnerability allows an out-of-bounds read within a potentially privileged process. On non-Debian platforms, xrdp tends to run as root. Potentially an out-of-bounds write can follow the out-of-bounds read. There is no denial-of-service impact, providing xrdp is running in forking mode. (CVE-2023-42822)
