| Title | Jens Axboe Fio 3.41 / master commit 84787ad NULL Pointer Dereference |
|---|
| Description | fio version 3.41 (master commit 84787ad) is vulnerable to a null pointer dereference in the function str_buffer_pattern_cb (options.c:1620). When parsing a jobfile, if the option buffer_pattern is specified without a value (e.g. buffer_pattern=), the parser passes a NULL pointer into the callback. The function then calls strlen() on this NULL pointer, causing a segmentation fault. |
