More information:

It was discovered that there were a large number of NULL pointer dereferences due to unchecked return values from malloc and friends in hiredis, a minimalistic C client library.

  • CVE-2020-7105

    async.c and dict.c in libhiredis.a in hiredis through 0.14.0 allow a NULL pointer dereference because malloc return values are unchecked.
