Description

This security bulletin contains information about 4 vulnerabilities.


1) Division by zero (CVE-ID: CVE-2021-20309)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: 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


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

The vulnerability exists due to a division by zero error in the WaveImage() function in MagickCore/visual-effects.c . A remote attacker can pass specially crafted image file to the application and crash it.


2) Division by zero (CVE-ID: CVE-2021-20311)

CWE-ID: CWE-369 - Divide By Zero

CVSSv4: 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


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

The vulnerability exists due to a division by zero error in the sRGBTransformImage() function in MagickCore/colorspace.c . A remote attacker can pass specially crafted image file to the application and crash it.


3) Integer overflow (CVE-ID: CVE-2021-20312)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 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


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

The vulnerability exists due to integer overflow in the WriteTHUMBNAILImage() function in coders/thumbnail.c. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

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


4) Information disclosure (CVE-ID: CVE-2021-20313)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to potential cipher leak when calculating signatures in TransformSignature() function in MagickCore/signature.c. A remote attacker can gain unauthorized access to sensitive information on the system.
