Subject: [PATCH 02/12] Remove const qualifier from parent_scope
|

|

If parent_scope is declared as const, the compiler may emit code that
|

assumes the value doesn't change, i.e. dereferencing the null pointer.

Subject: [PATCH 06/12] Fixes #116. Thanks to Jakub Wilk!
|
||||
|
||||
print_basic_hash() declares the output buffer as:
|
||||
|
||||
char hash_value[EVP_MAX_MD_SIZE * 2 + 1];
|
||||
|
||||
With the current OpenSSL versions, EVP_MAX_MD_SIZE * 2 + 1 is 129.
|
||||
However, fuzzy_hash_buf() requires an output buffer of size
|
||||
FUZZY_MAX_RESULT, which is 148.
