Mailscanner: Package updated with a patched version of bash

I've update the Mailscanner package and it looks like bash has been completely removed from the system instead.

# bash
bash: Command not found.

# find -f / bash
...
find: bash: No such file or directory

Could anybody please attach a gzipped patched binary here, to optionally replace it manually? Or maybe an URL to download the new .tgz?

There is no new tgz. For packages that require it, it is built into their PBI. Not sure why it didn't show up in mailscanner, but feel free to open a ticket in redmine for it if mailscanner is misbehaving because of its absence. It should also be the new FreeRADIUS2 PBI, so if you really want it, install that and copy the binary from there, then you could remove it if you want.

It is highly unlikely we'll make a stand-alone package just for bash.

I Installed freeradius2 package on my i386 NanoBSD box, and it didn't pull the bash binary as far as I can see:

/usr/local/bin(11): ls -la | grep bash
lrwxr-xr-x   1 root  wheel       36 Sep 27 19:31 bashbug -> /usr/pbi/freeradius-i386/bin/bashbug
/usr/local/bin(12): bash
bash: Command not found.

Confirming that bash is missing from Mailscanner too.

Nobody cares?

It's being looked at, they're apparently there on 2.2, though if you install one and then the other and remove one, the symlink goes with it.

There was another update to bash that needs put in anyhow, but it's mostly cosmetic (version bump) since the previous + patches has the fix already.

Since bash isn't there (and thus really isn't vulnerable ;D ) it isn't as high a priority, though it'll be fixed soon.

Please try last package version. Both PBIs were rebuilt and bash is inside.

Thanks.

Tried freeradius2 package by deleting it and installing it again. The patched bash binary is deployed on both i386 and amd64 platforms.
