Bug#976018: buster-pu: package cups/2.2.10-6+deb10u4
Package: release.debian.org
Severity: normal
Tags: buster
User: release.debian.org@packages.debian.org
Usertags: pu
X-Debbugs-Cc: debian-printing@lists.debian.org
#961345 affects Debian stable for certain printers/conditions; it's a daemon
crash with "invalid free()". As far as I could tell, it's likely a regression,
but due to causes external to CUPS.
This is the proposed changelog entry:
cups (2.2.10-6+deb10u4) buster; urgency=medium
* Backport upstream fix:
- backend,scheduler/ipp.c: Fix 'printer-alert' invalid free
(Closes: #961345)
-- Didier Raboud <odyx@debian.org> Sat, 28 Nov 2020 12:09:48 +0100
The only backported patch is from https://github.com/OpenPrinting/cups/pull/43,
which got merged upstream. Full debdiff attached.
Could I upload?
Cheers,
OdyX
