Description
This security bulletin contains information about 4 vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2020-10810)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the H5AC_unpin_entry() function located in H5AC.c. It allows an attacker to cause Denial of Service. A remote attacker can perform a denial of service (DoS) attack.
2) Heap-based buffer overflow (CVE-ID: CVE-2020-10809)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the Decompress() function in decompress.c. A remote attacker can exploit the vulnerability by sending a crafted file to the gif2h5 binary, trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.
3) Out-of-bounds read (CVE-ID: CVE-2020-10811)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the H5O__layout_decode() function in H5Olayout.c. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service attack.
4) NULL pointer dereference (CVE-ID: CVE-2020-10812)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the H5F_get_nrefs() function in H5Fquery.c. A remote attacker can perform a denial of service (DoS) attack.
