Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) 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.
2) Out-of-bounds write (CVE-ID: CVE-2021-32952)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the DGN file-reading procedure. A remote attacker can create a specially crafted DGN 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 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.
4) 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.
5) Improper Check for Unusual or Exceptional Conditions (CVE-ID: CVE-2021-32946)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to an improper check for unusual or exceptional conditions. A remote attacker can create a specially crafted DGN file, trick the victim into opening it and execute arbitrary code on the system.
6) 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.
7) 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.
8) 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.
9) Uncontrolled Memory Allocation (CVE-ID: CVE-2021-25173)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a memory allocation with excessive size issue when reading malformed DGN files. A remote attacker can cause a DoS condition.
10) Out-of-bounds write (CVE-ID: CVE-2021-31784)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error in the file-reading procedure. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
11) Stack-based buffer overflow (CVE-ID: CVE-2021-25178)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when the recover operation is run with malformed DXF and DWG files. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
12) Type Confusion (CVE-ID: CVE-2021-25177)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error when rendering malformed DXF and DWG files. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) NULL pointer dereference (CVE-ID: CVE-2021-25176)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to a NULL pointer dereference error when rendering malformed DXF and DWG files. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
14) Type conversion (CVE-ID: CVE-2021-25175)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to a memory corruption when rendering malformed DXF and DWG files. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
15) Buffer overflow (CVE-ID: CVE-2021-25174)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when reading malformed DGN files. A remote attacker can trigger memory corruption and cause a denial of service condition on the target system.
