Relevant environment:
Synaptic version 0.75.13
"vanilla" Debian 7.2
x86_64 platform
Xfce desktop environment, version 4.8

Problem: a user in the "sudo" group has a umask of 0027 (octal).  User runs Synaptic (menu or shell).  Xfce4 displays a dialog asking for user's password, which is entered.  Package manager runs without obvious problems.  A package is installed.  All files created during installation of the package are without any access allowed for "other."  Much hilarity ensues as users try in vain to use the installed packages.

There are workarounds, but this behavior as default can be very damaging to a system in fairly subtle ways.  Despite the existence of workarounds, I think this should be addressed in Synaptic itself as a matter of principle.
