Common Problems

ERROR MESSAGE:

 Insecure path while running setuid
 Insecure $ENV{PATH} while running setuid at /usr/bin/oowriter line 130.

ISSUE:

 After applying some patches, the system may add SetUID to perl executable. 
 Which causes some programs not to run:  oowriter 2.X , Konqueror, etc. . .

BACKGROUND:

$ which perl
/usr/bin/perl
$ ls -l `which perl`
-r-s--x--x  3 root root 1187244 2005-12-16 19:34 /usr/bin/perl

Ooopss... Perl with SETUID ??? Some systems like SuSE 9.3 don't like this...

$ chmod 755 `which perl`
$ ls -l `which perl`
 -rwxr-xr-x  3 root root 1187244 2005-12-16 19:34 /usr/bin/perl
