If the MIDAS Alarm property "write elog message" is enabled, an uninitialized variable "tag" is passed to
el_submit() and depending on your luck, cause a crash. "tag" is supposed to be and is now a NUL-
terminated string. The only other use of el_submit() is in mhttpd.cxx and mserver.c, where it is called

The HTTPS SSL certificate on ladd00.triumf.ca has been updated. Same as the old
certificate, the new one is self-signed and your web browser may complain about
that and ask you to "save a security exception".

26 Jul 2013, Konstantin Olchanski, Bug Report, abort on buffer overflow in odb.c::merge_records()
|
The odb.c function merge_records() has a fixed size array of 10000 bytes to handle the data and it
aborts with an assert() if passed data bigger than that. It is called from db_create_record() which
already allocates a data buffer of correct size for it's operations.

26 Jul 2013, Konstantin Olchanski, Bug Report, odbedit fixed size buffer overrun
|
odbedit uses a fixed size buffer for ODB data. If an array in ODB is bugger than this size,
db_get_data() correctly returns DB_TRUNCATED and there is no memory overwrite, but the following
code for printing the data does not know about this truncation and proceeds printing memory

26 Aug 2013, Konstantin Olchanski, Bug Fix, Enable cross-site requests in mhttpd
|
Javascript "AJAX" functions (and their MIDAS wrappers - ODBGet/ODBSet) are subject to something called
"same origin policy" intended to prevent something called "cross-site scripting attacks", i.e. see

13 Sep 2013, Konstantin Olchanski, Bug Report, mhttpd truncates string variables to 32 characters
|
I can confirm part of the problem - the new inline-edit function - after you finish editing - shows you what you
have typed, not what's actually in ODB - at the very end it should do an ODBGet() to load the actual ODB
