msdia.dll in Microsoft Debug Interface Access (DIA) SDK, as distributed in Microsoft Visual Studio before 2013, does not properly validate an unspecified variable before use in calculating a dynamic-call address, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted PDB file.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
