An initial request is -made to get the `fru.size`, which is used as the size for the allocation -of `spd_data`. Inside a loop, further requests are performed to get the -copy sizes which are not checked before being used as the size for a -copy into the buffer. ---- - lib/dimm_spd.c | 9 ++++++++- - 1 file changed, 8 insertions(+), 1 deletion(-) - -diff --git a/lib/dimm_spd.c b/lib/dimm_spd.c -index 163a2c2..d559cb4 100644 ---- a/lib/dimm_spd.c -+++ b/lib/dimm_spd.c -@@ -1621,7 +1621,7 @@ ipmi_spd_print_fru(struct ipmi_intf * intf, uint8_t id) - struct ipmi_rq req; - struct fru_info fru; - uint8_t *spd_data, msg_data[4]; -- int len, offset; -+ uint32_t len, offset; - - msg_data[0] = id; - -@@ -1697,6 +1697,13 @@ ipmi_spd_print_fru(struct ipmi_intf * intf, uint8_t id) - } - - len = rsp->data[0]; -+ if(rsp->data_len < 1 -+ || len > rsp->data_len - 1 -+ || len > fru.size - offset) -+ { -+ printf(" Not enough buffer size"); -+ return -1; -+ } - memcpy(&spd_data[offset], rsp->data + 1, len); - offset += len; - } while (offset < fru.size); --- -2.20.1 - |
