Description

This security bulletin contains information about 5 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2020-3989)

CWE-ID: CWE-119 - Memory corruption

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


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

The vulnerability exists due to a boundary error in Cortado ThinPrint component. A remote authenticated attacker can trigger memory corruption and cause a denial of service condition on the target system.


2) Integer overflow (CVE-ID: CVE-2020-3990)

CWE-ID: CWE-190 - Integer overflow

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


The vulnerability allows a remote attacker to gain access to sensitive information on the system.

The vulnerability exists due to integer overflow in Cortado ThinPrint component. A remote authenticated attacker can pass specially crafted data to the application, trigger integer overflow and gain access to sensitive information on the target system.


3) Out-of-bounds read (CVE-ID: CVE-2020-3988)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/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 a boundary condition in the Cortado ThinPrint component in JPEG2000 parser. A remote authenticated attacker can use a specially crafted EMF file, trigger out-of-bounds read error and read contents of memory on the system or cause a denial of service (DoS) condition.


4) Out-of-bounds read (CVE-ID: CVE-2020-3987)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/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 a boundary condition in the Cortado ThinPrint component in EMR STRETCHDIBITS parser. A remote authenticated attacker can use a specially crafted EMF file, trigger out-of-bounds read error and read contents of memory on the system or cause a denial of service (DoS) condition.


5) Out-of-bounds read (CVE-ID: CVE-2020-3986)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/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 a boundary condition in the Cortado ThinPrint component in EMF parser. A remote authenticated attacker can use a specially crafted EMF file, trigger out-of-bounds read error and read contents of memory on the system or cause a denial of service (DoS) condition.
