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

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)

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)

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)

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)

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.
