[edk2] [PATCH v2] SecurityPkg: Fix potential bug in Security Boot dxe.
Posted by Zhang Lubo 7 years, 8 months ago 
v2: update hash value in SecureBootConfig.vfr to keep
them consistent with macro definition in SecureBootConfigImpl.h

since we removed the sha-1 definition in Hash table
and related macro, but the macro definition HashAlg index
may be value 4 which is exceed the range of the Hash
table array.
