Bug#1071159: bookworm-pu: package glib2.0/2.74.6-2+deb12u3

[Simon McVittie]

Package: release.debian.org
Severity: normal
Tags: bookworm
User: release.debian.org at packages.debian.org
Usertags: pu
X-Debbugs-Cc: glib2.0 at packages.debian.org
Control: affects -1 + src:glib2.0

[ Reason ]
Fix a minor memory leak introduced by recent security updates.

[ Impact ]
In an unusual situation that I believe is very rare in practice, programs
using D-Bus via GLib will leak memory.

(Specifically, that situation is: the program allocates a GDBus message
with a non-empty body, then replaces the message body with something
different, and the original body is leaked. The only use I'm aware of
for editing messages in this way in Debian was in a hack to avoid gdm3
upgrades from jessie to stretch being unable to unlock the screensaver,
by rewriting D-Bus messages in-place, and that was removed between
stretch and buster.)

[ Tests ]
There is a relatively extensive test suite, which is how the leak was found
in the first place, and it still passes.

The proposed version is also working well to run the GNOME environment
where I'm typing this.

[ Risks ]
Low risk. The change is small and obviously correct, already migrated
to testing, and was included in the backported security fix for Debian
10 LTS. It was discovered too late to be included with the more serious
regression fixes in Debian 12 and 11, and in any case would not have been
urgent enough to justify delaying fixes for the more serious regression.

[ Checklist ]
  [x] *all* changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [x] attach debdiff against the package in (old)stable
      - the debdiff is vs. bookworm-security, I assume that's OK
  [x] the issue is verified as fixed in unstable

[ Changes ]
All changes are for this single bug fix.

[ Other info ]
I already uploaded to -proposed-updates.

The security team agreed with my assessment that this is not important
enough to issue another DSA update.

Thanks,
