|
|
|
|
=== Description ===
|
|
User-supplied variable "generator" copied to 128 byte buffer "query"
|
|
size of query variable. So
|
|
its cause off-by-one overflow. You can see [1] snprintf copy statement
|
|
to "query" variable.
|
|
|
|
/* {{{ proto int ibase_gen_id(string generator [, int increment [,
|
|
resource link_identifier ]])
|
|
Increments the named generator and returns its new value */

[1] snprintf(query, sizeof(query), "SELECT GEN_ID(%s,%ld) FROM
|
|

|
|
...

|
}
|
|
|
|
=== Patch ===
|
|
Replace [1] with [2].
|
|
|
|
--- [1] snprintf(query, sizeof(query), "SELECT GEN_ID(%s,%ld) FROM
|
|
rdb$database", generator, inc);
|
|
+++ [2] snprintf(query, sizeof(query) - 1 "SELECT GEN_ID(%s,%ld)
|
|
FROM rdb$database", generator, inc);
