Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Value of member ELF_T_NUM has been changed from 17 to 15.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

libelf.h
[+] enum Elf_Type (1)

to the top

Problems with Data Types, Low Severity (2)

	Change	Effect
1	The member ELF_T_VDEF has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
2	The member ELF_T_VNEED has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.

libelf.h
[+] enum Elf_Type (2)

to the top

Problems with Symbols, Low Severity (1)

	Change	Effect
1	Base type of 1st parameter __name has been changed from unsigned char to char.	Replacement of parameter base type may indicate a change in its semantic meaning.

Problems with Constants, Low Severity (13)

	Change	Effect
1	The constant __LIBELF_SYMBOL_VERSIONS with value 1 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF32_FSZ_ADDR with value 4 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF32_FSZ_HALF with value 2 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF32_FSZ_OFF with value 4 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF32_FSZ_SWORD with value 4 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF32_FSZ_WORD with value 4 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_ADDR with value 8 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_HALF with value 2 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_OFF with value 8 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_SWORD with value 4 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_SXWORD with value 8 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_WORD with value 4 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.

	Change	Effect
1	The constant ELF64_FSZ_XWORD with value 8 has been removed.	The value of this constant may no longer be properly handled by new-version library functions.
