Debian 11: DLA-3977-1 critical update for xfpt buffer overflow issue

An issue has been found in xfpt, a tool to generate XML from plain tex.
The issue is about bad handling of input data, which may result in a
stack-based buffer overflow and execution of arbitrary code, when
processing specially crafted files.


For Debian 11 bullseye, this problem has been fixed in version
0.11-1+deb11u1.

We recommend that you upgrade your xfpt packages.
