CVE-2019-9232

There is a possible out of bounds read due to a missing bounds check.
This could lead to remote information disclosure with no additional
execution privileges needed. User interaction is not needed for
exploitation.

CVE-2019-9433

There is a possible information disclosure due to improper input
validation. This could lead to remote information disclosure with no
additional execution privileges needed. User interaction is needed for
