Description Enrico Scholz 2001-06-29 07:06:40 EDT
Description of Problem:

All env-variables of jobs started by at-3.1.8-18 get empty values. The
man-page says they are retained.

The at-3.1.8-env.patch seems to be responsibly. There the last hunk

-           fwrite(*atenv, sizeof(char), eqp - *atenv - 1, fp);
+           fwrite(*atenv, sizeof(char), eqp - *atenv, fp); 

should be removed. Else entries like

| <var>=<values>; export <var>=

will be created.

| <var>=<values>; export <var>

would be correct.

How Reproducible:


Steps to Reproduce:
1. echo 'test' | at now+5min
2. at -c <number of the job>

Actual Results:

PWD=/home/ensc; export PWD=
http_proxy=http://www-cache:3128/; export http_proxy=

Expected Results:

PWD=/home/ensc; export PWD
http_proxy=http://www-cache:3128/; export http_proxy

Sorry, my suggested patch was erroneous and reopens perhaps the door to a local
attack (have overseen that at is SUID and user can give a manipulated env like
