Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU78285

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-2023-25433

CWE-ID: CWE-119 - Memory corruption

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 error when processing TIFF images within the rotateImage()  function in /libtiff/tools/tiffcrop.c. A remote attacker can pass a specially crafted image to the application, trigger memory corruption and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

openEuler: 20.03 LTS SP1 - 22.03 LTS

libtiff-help: before 4.3.0-14

2) Buffer overflow

EUVDB-ID: #VU78287

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2023-26966

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the uv_encode() function. A remote attacker can pass a specially crafted TIFF file to the application, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's repository.
