Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Out-of-bounds read (CVE-ID: CVE-2019-17533)

The vulnerability allows a remote attacker to gain access to potentially sensitive information or perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the Mat_VarReadNextInfo4() function in mat4.c in matio when processing a certain '' character. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds read error and read contents of memory on the system or crash the application.


2) Memory leak (CVE-ID: CVE-2019-20052)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due memory leak in Mat_VarCalloc() function in mat.c, because SafeMulDims does not consider the rank==0 case. A remote attacker can perform denial of service attack.


3) Out-of-bounds read (CVE-ID: CVE-2019-20020)

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

The vulnerability exists due to a boundary condition in ReadNextStructField() function in mat5.c. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.


4) Resource exhaustion (CVE-ID: CVE-2019-20019)

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

The vulnerability exists due to attempted excessive memory allocation within Mat_VarRead5() function in mat5.c. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


5) Out-of-bounds read (CVE-ID: CVE-2019-20018)

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

The vulnerability exists due to a boundary condition within the ReadNextCell() function in mat5.c. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.


6) Out-of-bounds read (CVE-ID: CVE-2019-20017)

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

The vulnerability exists due to a stack-based buffer over-read within the Mat_VarReadNextInfo5() in mat5.c. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
