Ubuntu update for libjpeg-turbo

1) Infinite loop

EUVDB-ID: #VU24199

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-2018-11813

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

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

The vulnerability exists due to infinite loop in read_pixel() function in rdtarga.c when processing EOF (end-of-line) characters. A remote attacker can use a specially crafted image to consume all available system resources and cause denial of service conditions.

Mitigation

Update the affected package libjpeg-turbo to the latest version.

Vulnerable software versions

2) Out-of-bounds read

EUVDB-ID: #VU24203

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-14498

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition when processing a crafted 8-bit BMP in which one or more of the color indices is out of range for the number of palette entries within the get_8bit_row in rdbmp.c. A remote attacker can create a specially crafted file, pass it to the application, trigger out-of-bounds read error and crash the affected application.

Mitigation

Update the affected package libjpeg-turbo to the latest version.

3) Buffer overflow

EUVDB-ID: #VU29121

Risk: Medium

CVSSv3.1: 4.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-14152

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error in "jpeg_mem_available()" function in "jmemnobs.c" file in djpeg. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger memory corruption and gain access to sensitive information or cause a denial of service condition on the target system.

Mitigation

Update the affected package libjpeg-turbo to the latest version.

4) Stack-based buffer overflow

EUVDB-ID: #VU54089

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-17541

CWE-ID: CWE-121 - Stack-based buffer overflow

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 in the in the "transform" component in Libjpeg-turb. A remote attacker can create a specially crafted JPEG image, pass it to the affected aplication, trigger a stack-based buffer overflow and execute arbitrary code on the target system.

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

Mitigation

Update the affected package libjpeg-turbo to the latest version.
