Title:
cupsd 2.4.7-1.2ubuntu5 on noble crashes due to recently backported
commits from 2.4.x git
Status in cups package in Ubuntu:
Fix Released
Bug description:
While checking out the latest versions of cups (2.4.7-1.2ubuntu4 and
2.4.7-1.2ubuntu5),
I noticed that cupsd crashes consistently after closing my Firefox tab /
window.
The title of the crash (from the bug-report window) is "cupsd crashed with
SIGSEGV in ???()"
I'm running the noble-desktop-amd64.iso from 2024-03-25 after applying
some updates from the noble and noble-proposed pockets.
Reproduction steps:
1. Open Firefox and manage CUPS on http://localhost:631
2. Go to Administration -> Printers -> Add Printer and choose your printer
3. Add your printer (I used the ipps:// protocol to manage the printer)
4. After clicking the "Add printer" button, immediately close your Firefox tab
5. cupsd will crash and Ubuntu will display a bug-report popup
Versions:
Firefox - 124.0.1-1 r4033
CUPS - 2.4.7-1.2ubuntu5
Printer:
Lexmark MS415dn (supported)
I am unable to reproduce this bug on versions prior to
2.4.7-1.2ubuntu4 (Tried with 2.4.7-1.2ubuntu1 and 2.4.7-1.2ubuntu2).
Versions 2.4.7-1.2ubuntu4 and 2.4.7-1.2ubuntu5 only backported commits from
the 2.4.x upstream git branch, so I also opened an issue on GitHub:
https://github.com/OpenPrinting/cups/issues/934
