Problems with Symbols, High Severity (4)

	Change	Effect
1	Parameter ca_crl of type x509_crl* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Parameter buf of type char* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.
2	Parameter size of type size_t has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

	Change	Effect
1	Parameter ca_crl of type x509_crl* has been added to the calling stack at the middle position.	Layout of parameter's stack has been changed and therefore parameters at higher positions in the stack may be incorrectly initialized by applications.

Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Field ca_crl has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

[+] struct _ssl_context (1)

Problems with Symbols, Medium Severity (2)

	Change	Effect
1	The pointer level of return value has been decreased from 1 to 0.	Applications may try to access unallocated memory by the dereferencing of new return value and therefore cause a crash.

	Change	Effect
1	The pointer level of 2nd parameter end has been decreased from 1 to 0.	The library function will treat the parameter as the lower-dimension array and will not read all elements. This may change the behavior of applications. NOTE: if this is out-parameter then this change may cause a crash of applications.

Problems with Data Types, Low Severity (3)

	Change	Effect
1	Type of field rk has been changed from unsigned long[68] to uint32_t[68].	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Size of this type has been changed from 2168 bytes to 2172 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Type of field k has been changed from unsigned long[4] to uint32_t[4].	Replacement of the field data type may indicate a change in the semantic meaning of the field.

Problems with Symbols, Low Severity (6)

	Change	Effect
1	1st parameter prefix has been renamed to buf.	Renaming of a parameter may indicate a change in its semantic meaning.
2	Type of return value has been changed from char* to int.	Replacement of return type may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter crt has been renamed to chain.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	1st parameter crt has been renamed to chain.	Renaming of a parameter may indicate a change in its semantic meaning.

	Change	Effect
1	2nd parameter end has been renamed to size.	Renaming of a parameter may indicate a change in its semantic meaning.
2	Type of 2nd parameter end has been changed from char* to size_t.	Replacement of parameter data type may indicate a change in its semantic meaning.
