Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2021-3474)

The vulnerability allows a remote attacker to perform a denial of service (DoS) on the target system.

The vulnerability exists due to integer overflow in the FastHufDecoder. A remote attacker can pass specially crafted file, trigger integer overflow and cause a denial of service condition on the target system.

2) Out-of-bounds read (CVE-ID: CVE-2021-3477)

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

The vulnerability exists due to a boundary condition within the deep tile sample size calculations. A remote attacker can create a specially crafted file, trigger out-of-bounds read error and read contents of memory on the system.

3) Integer overflow (CVE-ID: CVE-2021-3475)

The vulnerability allows a remote attacker to perform a denial of service (DoS) on the target system.

The vulnerability exists due to integer overflow. A remote attacker can pass specially crafted file, trigger integer overflow and cause a denial of service condition on the target system.

4) NULL pointer dereference (CVE-ID: CVE-2021-20296)

The 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 Dwa decompression functionality. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.

5) Integer overflow (CVE-ID: CVE-2021-3476)

The vulnerability allows a remote attacker to perform a denial of service (DoS) on the target system.

The vulnerability exists due to integer overflow in B44 uncompression functionality. A remote attacker can pass specially crafted file, trigger integer overflow and cause a denial of service condition on the target system.

6) Resource exhaustion (CVE-ID: CVE-2021-3479)

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

The vulnerability exists due to application does not properly control consumption of internal resources within the Scanline API functionality. A remote attacker can use a specially crafted file, trigger resource exhaustion and perform a denial of service (DoS) attack.
