Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU63328

Risk: Medium

CVSSv4.0: 4.6 [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:Green]

CVE-ID: CVE-2022-0562

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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 memcpy() function within TIFFReadDirectory() in tif_dirread.c. A remote attacker can trick victim to open specially crafted TIFF file and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

3) Out-of-bounds read

EUVDB-ID: #VU63795

Risk: Medium

CVSSv4.0: 4.6 [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:Green]

CVE-ID: CVE-2022-22844

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition in the _TIFFmemcpy() function in tif_unix.c in certain situations involving a custom tag and 0x0200 as the second word of the DE field. A remote attacker can pass a specially crafted file and perform a denial of service attack.

Mitigation

Install updates from vendor's repository.
