Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2020-36148)

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 verifyAttribute function in the libmysofa library 0.5 - 1.1. A remote attacker can perform a denial of service (DoS) attack.


2) NULL pointer dereference (CVE-ID: CVE-2020-36149)

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 changeAttribute function in the libmysofa library 0.5 - 1.1. A remote attacker can perform a denial of service (DoS) attack.


3) Heap-based buffer overflow (CVE-ID: CVE-2020-36150)

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

The vulnerability exists due to a boundary error within the loudness() function in the libmysofa library. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

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


4) Heap-based buffer overflow (CVE-ID: CVE-2020-36151)

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

The vulnerability exists due to a boundary error within the mysofa_resampler_reset_mem() function in the libmysofa library. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and execute arbitrary code on the target system.

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


5) Buffer overflow (CVE-ID: CVE-2020-36152)

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

The vulnerability exists due to a boundary error when processing SOFA files within the readDataVar() function in hdf/dataobject.c. A remote attacker can create a specially crafted SOFA file, pass it to he affected application, trigger memory corruption and execute arbitrary code on the target system.

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