Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2021-45829)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.


2) Heap-based buffer overflow (CVE-ID: CVE-2021-45830)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the H5F_addr_decode_len() function in /hdf5/src/H5Fint.c. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.


3) Stack-based buffer overflow (CVE-ID: CVE-2021-45833)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in within the H5D__create_chunk_file_map_hyper() function in /hdf5/src/H5Dchunk.c. A remote attacker can send specially crafted data to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.

4) Stack-based buffer overflow (CVE-ID: CVE-2021-45832)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in hdf5/src/H5Eint.c. A remote attacker can send specially crafted data to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.


5) Untrusted Pointer Dereference (CVE-ID: CVE-2021-46243)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to untrusted pointer dereference error within the H5O__dtype_decode_helper() function in hdf5/src/H5Odtype.c. A remote attacker can pass specially crafted data to the application, trigger a pointer dereference and perform a denial of service (DoS) attack.


6) Use-after-free (CVE-ID: CVE-2021-46242)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the H5AC_unpin_entry component. A remote attacker can pass specially crafted input to the application, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


7) Division by zero (CVE-ID: CVE-2021-46244)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a divide by zero error within the H5T__complete_copy() function in /hdf5/src/H5T.c. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
