## Notes

---

### [iconstantin](https://launchpad.net/~iconstantin)

Issue impacts GhostPCL, we currently do not build with
PCL support.

### [mdeslaur](https://launchpad.net/~mdeslaur)

First commit fixes pcl/pcl/pcstatus.c, while this file exists
in the focal source package (only), it does not appear to get
built as debian/rules contains --without-pcl. The reproducer
in the upstream bug needs PCL support to work.
The second commit does fix a file that is built in Ubuntu
ghostscript packages, but there is no indication that it is
security relevant without the PCL support. Marking as "low"
for now until further information becomes available.
