Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2019-20015)

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

The vulnerability exists due to improper input validation in "dwg_decode_LWPOLYLINE_private" in "dwg.spec". A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Double Free (CVE-ID: CVE-2019-20014)

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

The vulnerability exists due to a boundary error in "dwg_free" in "free.c". A remote attacker can trigger double free error and execute arbitrary code on the target system.

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


3) Resource exhaustion (CVE-ID: CVE-2019-20012)

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

The vulnerability exists due to improper input validation in "dwg_decode_HATCH_private" in "dwg.spec". A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Out-of-bounds read (CVE-ID: CVE-2019-20011)

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

The vulnerability exists due to a boundary condition in decode_R13_R2000 in decode.c. A remote attacker can trigger out-of-bounds read error and cause a denial of service contrition on the target system.


5) Use-after-free (CVE-ID: CVE-2019-20010)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in "resolve_objectref_vector" in "decode.c". A remote attacker can trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


6) Resource exhaustion (CVE-ID: CVE-2019-20009)

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

The vulnerability exists due to improper input validation in "dwg_decode_SPLINE_private" in "dwg.spec". A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


7) Resource exhaustion (CVE-ID: CVE-2019-20013)

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

The vulnerability exists due to improper input validation in "decode_3dsolid" in "dwg.spec". A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
