Log Message:
-----------
file_store_any2obj.c: validate blob length before allocation
Both msblob2obj_decode() and pvk2obj_decode() computed an
attacker-influenced buffer size (from `bitlen`, or from
`saltlen + keylen`) and passed it to BUF_MEM_grow() without an
upper bound.
Resolves #31684
Fixes: f40c5f2c53b9 "PROV & STORE: Make the 'file:' store loader understand more binary formats"
Fixes: 0f5493e60b9e "storemgmt: Validate msblob length before buffer allocation"
