Subject: bash: tab completion fails with awk error when first arg is gdb and second arg is subshell expansion

Date: Wed, 15 Jun 2005 17:01:51 -0500

Package: bash
Version: 3.0-15
Severity: normal

$ gdb $(which svn) svn_exawk: {if ($1 ~ /^$(which
awk:            ^ unterminated regexp
awk: fatal: Unmatched ( or \(: /^$(which/

Nasty.

(

I typed:

gdb $(which svn) svn_e<TAB>

)

* Replacing "gdb" with "ls" makes the problem go away.
* Replacing "$(which svn)" with "/usr/bin/svn" suppresses the error, but the
  completion does nothing useful.  It apparently doesn't know what to look for,
  and it certainly doesn't offer any completions in $PWD.

This has been fixed for the next release, although there are probably
more vulnerabilities of this kind elsewhere in the code.

Eh?  Brandon wasn't talking about vulnerabilities; are you sure this
is the right bug?

Yes. I was using the word in a broad sense and meant that the code is
almost certainly vulnerable to this bug in other places.
