Package: collectd-core
Version: 4.10.1-1+squeeze2
Severity: normal
When "notify_email" plugin is used, and if a configuration option for it
is not OK, collectd crashes. Example of a wrong configuration:
LoadPlugin notify_email
<Plugin notify_email>
From collectd@host
Recipient admin@host
</Plugin>
The problem is that the values should be surrounded by quotes, however
this seems to be ignored and then the value becomes "collectd host",
and as a result an error occurs when collectd tries to use this as
a valid email address.
I am not sure what the upstream's idea of a proper fix is, so no
patch is attached, but I believe I have included enough information
so they can fix this easily.
The crash occurs in:
notify_email.c, function "print_recipient_status":
if (status->text[strlen(status->text) - 2] == '\r')
status->text[strlen(status->text) - 2] = 0;
Here "status->text" is a NULL pointer so a check needs to be added
to guard against it, or even better, a warning should be generated
when parsing a config file.
