Subject: [PATCH] lanp: Fix buffer overflows in get_lan_param_select
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8

Partial fix for CVE-2020-5208, see
|
||
https://github.com/ipmitool/ipmitool/security/advisories/GHSA-g659-9qxw-p7cp
|
||
|
||
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.
