Presumably this means there were three cases found by Stefan Roas but
the third wasn't exploitable. CVE-2015-2788 is for:
- char err[80];
- sprintf(err, "String truncation (SQL_VARYING): attempted to bind %lu octets to column sized %lu"
- char err[80];
- sprintf(err, "String truncation (SQL_TEXT): attempted to bind %lu octets to column sized %lu"
For the third one:
- char err[80];
- sprintf(err, "You have not provided a value for non-nullable parameter #%d.", i);
"You have not provided a value for non-nullable
parameter #-9223372036854775807.\0" is 80 characters.
Also, the scope of this CVE ID does not include any unreported or
later-reported buffer overflows found and fixed by Damyan Ivanov,
e.g., ones in the
