Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
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
DescriptionThe 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.
MitigationUpdate the affected package libjpeg-turbo to the latest version.
Vulnerable software versionsUbuntu: 18.04 - 20.04
libjpeg-turbo8 (Ubuntu package): before 2.0.3-0ubuntu1.20.04.3
libturbojpeg (Ubuntu package): before 2.0.3-0ubuntu1.20.04.3
External linkshttp://ubuntu.com/security/notices/USN-5631-1
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) 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
DescriptionThe 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.
MitigationUpdate the affected package libjpeg-turbo to the latest version.

3) NULL pointer dereference
EUVDB-ID: #VU67589
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-35538
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe 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 jcopy_sample_rows() function. A remote attacker can pass specially crafted input to the affected application and perform a denial of service (DoS) attack.
MitigationUpdate the affected package libjpeg-turbo to the latest version.
Vulnerable software versionsUbuntu: 18.04 - 20.04

4) Out-of-bounds write
EUVDB-ID: #VU67590
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-46822
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing images within the get_word_rgb_row() function in rdppm.c. A remote attacker can pass a specially crafted file to the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.
MitigationUpdate the affected package libjpeg-turbo to the latest version.
