Problems with Data Types, Low Severity (18)

	Change	Effect
1	Name of member with value 8 has been changed from ELF_C_READ_MMAP to ELF_C_NUM.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	The member ELF_C_EMPTY has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
3	The member ELF_C_RDWR_MMAP has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
4	The member ELF_C_READ_MMAP_PRIVATE has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
5	The member ELF_C_WRITE_MMAP has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.

	Change	Effect
1	Name of member with value 16 has been changed from ELF_T_VDAUX to ELF_T_VNEED.	Applications may execute a wrong branch of code in the library and therefore change the behavior.
2	The member ELF_T_AUXV has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
3	The member ELF_T_GNUHASH has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
4	The member ELF_T_LIB has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
5	The member ELF_T_MOVE has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
6	The member ELF_T_NHDR has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
7	The member ELF_T_SYMINFO has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.
8	The member ELF_T_VNAUX has been removed.	This may result in crash or incorrect behavior of applications because the library may not handle removed member anymore.

	Change	Effect
1	Size of this type has been changed from 32 bytes to 28 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Type of field ar_gid has been changed from gid_t to long.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
3	Type of field ar_mode has been changed from mode_t to unsigned long.	Replacement of the field data type may indicate a change in the semantic meaning of the field.
4	Type of field ar_uid has been changed from uid_t to long.	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 28 bytes to 24 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

Problems with Constants (2)

	Change	Effect
1	The value of constant ELF_F_DIRTY has been changed from ELF_F_DIRTY to 0x1.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

	Change	Effect
1	The value of constant ELF_F_LAYOUT has been changed from ELF_F_LAYOUT to 0x4.	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.
