kroki/tomash@moonlight.intranet 1917a99270 BUG#21206: memory corruption when too many cursors are opened at once ... Too many cursors (more than 1024) could lead to memory corruption. This affects both, stored routines and C API cursors, and the threshold is per-server, not per-connection. Similarly, the corruption could happen when the server was under heavy load (executing more than 1024 simultaneous complex queries), and this is the reason why this bug is fixed in 4.1, which doesn't support cursors. The corruption was caused by a bug in the temporary tables code, when an attempt to create a table could lead to a write beyond allocated space. Note, that only internal tables were affected (the tables created internally by the server to resolve the query), not tables created with CREATE TEMPORARY TABLE. Another pre-condition for the bug is TRUE value of --temp-pool startup option, which, however, is a default. The cause of a bug was that random memory was overwritten in bitmap_set_next() due to out-of-bound memory access.		2006-07-27 13:59:15 +04:00
