Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2021-32944)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the DGN file-reading procedure. A remote attacker can trick a victim to open a specially crafted file and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Out-of-bounds write (CVE-ID: CVE-2021-32936)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the DXF file-recovering procedure. A remote attacker can create a specially crafted DXF file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
3) Out-of-bounds write (CVE-ID: CVE-2021-32948)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the DWG file-reading procedure. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
4) Out-of-bounds read (CVE-ID: CVE-2021-32938)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker can create a specially crafted DWG file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system, or cause a denial of service (DoS) attack.
5) Out-of-bounds read (CVE-ID: CVE-2021-32940)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the DWG file-recovering procedure. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system, or cause a denial of service (DoS) attack.
6) Out-of-bounds read (CVE-ID: CVE-2021-32950)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the parsing of DXF files. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system, or cause a denial of service (DoS) attack.
7) NULL pointer dereference (CVE-ID: CVE-2021-33717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can use a specially crafted CGM file and perform a denial of service (DoS) attack.
