Package: emacspeak-ss Version: 1.12.1-7 Severity: minor User: trei...@debian.org Usertags: colis-shparser
Hi, the prerm script of emacspeak-ss contains a perl script as a here document (which in reality is read by perl -x) like this: perl -x $0 # execute this file as a perl program true <<EOF # bash discards everything from here to EOF [some perl code] __END__ EOF Written this way, the here document is expanded by the shell. The result of this expansion is sent to the true command, and the perl interpreter sees the original unexpanded perl script. The potential problem is that shell expansion may have side effects through subshell expansion and parameter expansion with assignments, so this seems unsafe. We suggest to replace the second line of the above snippet by true <<'EOF' since the quote character in the delimiter tells the shell to not expand the here docment. -Yann and Ralf. -- Ralf Treinen Institut de Recherche en Informatique Fondamentale Équipe Preuves, Programmes et Systèmes Université Paris Diderot, Paris, France. http://www.irif.fr/~treinen/
