Subject: [dpdk-stable] [PATCH 18.11] examples/fips_validation: fix buffer overflow
Date: Wed,  2 Dec 2020 15:39:47 +0100
Message-ID: <> (raw)

[ upstream commit 9275af3bd9faa0337b418736bb622704d158fbac ]

If the file name is larger than MAX_STRING_SIZE (64), strcpy()
will overwrite the content of memory.

Replace strcpy() by rte_strscpy(), check its return value, and
increase file_name size to 256.

Fixes: 3d0fad56b74a ("examples/fips_validation: add crypto FIPS application")

Most of the original commit has been removed, because a part of the
issue was introduced by commit efe3a8dbb66e ("examples/fips_validation:
support TDES ECB"), and it is not present in this branch.

Only the length check on the device name remains.
