Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Out-of-bounds read

EUVDB-ID: #VU68820

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-2953

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition in the extractImageSection() function in tools/tiffcrop.c. A remote attacker can pass a specially crafted TIFF file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.
