Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU63374

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0908

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 TIFFFetchNormalTag () in tif_dirread.c. A remote attacker can pass specially crafted TIFF file to the application and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
