+ Partial fix for CVE-2020-5208, see
+ https://github.com/ipmitool/ipmitool/security/advisories/GHSA-g659-9qxw-p7cp
+ .
+ The `read_fru_area_section` function only performs size validation of
+ requested read size, and falsely assumes that the IPMI message will not
+ respond with more than the requested amount of data; it uses the
+ unvalidated response size to copy into `frubuf`. If the response is
+ larger than the request, this can result in overflowing the buffer.
+ .
+ The same issue affects the `read_fru_area` function.

+
+The `ipmi_spd_print_fru` function has a similar issue as the one fixed
+by the previous commit in `read_fru_area_section`. 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.

+
+The `get_lan_param_select` function is missing a validation check on the
+response’s `data_len`, which it then returns to caller functions, where
+stack buffer overflow can occur.

+Subject: [PATCH 6/6] fru, sdr: Fix id_string buffer overflows
+
+Final part of the fixes for CVE-2020-5208, see
+https://github.com/ipmitool/ipmitool/security/advisories/GHSA-g659-9qxw-p7cp
+
+9 variants of stack buffer overflow when parsing `id_string` field of
+SDR records returned from `CMD_GET_SDR` command.
+
+SDR record structs have an `id_code` field, and an `id_string` `char`
+array.
+
+The length of `id_string` is calculated as `(id_code & 0x1f) + 1`,
+which can be larger than expected 16 characters (if `id_code = 0xff`,
+then length will be `(0xff & 0x1f) + 1 = 32`).
+
+In numerous places, this can cause stack buffer overflow when copying
+into fixed buffer of size `17` bytes from this calculated length.
