Vulnerability from variot

An out-of-bounds write issue exists in the DGN file-reading procedure in the Drawings SDK (Version 2022.4 and prior) resulting from the lack of proper validation of user-supplied data. This can result in a write past the end of an allocated buffer and allow attackers to cause a denial-of-service condition or execute code in the context of the current process. Open Design Alliance Provided by Drawings SDK is a drafting software development kit. This product contains multiple vulnerabilities listed below. * Out-of-bounds read (CWE-125) - CVE-2021-32938 It was * Out-of-bounds writing (CWE-787) - CVE-2021-32936 It was * Out-of-bounds read (CWE-125) - CVE-2021-32940 It was * DGN Improper checking of files for abnormal or exceptional conditions (CWE-754) - CVE-2021-32946 It was * Out-of-bounds writing (CWE-787) - CVE-2021-32948 It was * Out-of-bounds read (CWE-125) - CVE-2021-32950 It was * Out-of-bounds writing (CWE-787) - CVE-2021-32952 It was * Use of freed memory (use-after-free) (CWE-416) - CVE-2021-32944The expected impact depends on each vulnerability, but it may be affected as follows. It was * crafted by the attacker DWG Denial of service by opening the file (DoS) triggering a condition or reading sensitive information from memory - CVE-2021-32938 It was * crafted by the attacker DXF Denial of service by opening files via recovery (DoS) state is triggered or code is executed - CVE-2021-32936 It was * crafted by the attacker DWG Denial of service by opening files via recovery (DoS) triggering a condition or reading sensitive information from memory - CVE-2021-32940 It was * crafted by the attacker DGN Denial of service by reading the file (DoS) state is triggered or code is executed - CVE-2021-32946 , CVE-2021-32952 It was * crafted by the attacker DWG Denial of service by opening the file (DoS) state is triggered or code is executed - CVE-2021-32948 It was * crafted by the attacker DXF Denial of service by opening the file (DoS) triggering a condition or reading sensitive information from memory - CVE-2021-32950 It was * Crafted by an attacker by an attacker DGN Denial of service by opening the file (DoS) A condition is triggered or arbitrary code is executed - CVE-2021-32944. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of DGN files. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements

    "data": "An out-of-bounds write issue exists in the DGN file-reading procedure in the Drawings SDK (Version 2022.4 and prior) resulting from the lack of proper validation of user-supplied data. This can result in a write past the end of an allocated buffer and allow attackers to cause a denial-of-service condition or execute code in the context of the current process. Open Design Alliance Provided by Drawings SDK is a drafting software development kit. This product contains multiple vulnerabilities listed below. * Out-of-bounds read (CWE-125) - CVE-2021-32938 It was * Out-of-bounds writing (CWE-787) - CVE-2021-32936 It was * Out-of-bounds read (CWE-125) - CVE-2021-32940 It was * DGN Improper checking of files for abnormal or exceptional conditions (CWE-754) - CVE-2021-32946 It was * Out-of-bounds writing (CWE-787) - CVE-2021-32948 It was * Out-of-bounds read (CWE-125) - CVE-2021-32950 It was * Out-of-bounds writing (CWE-787) - CVE-2021-32952 It was * Use of freed memory (use-after-free) (CWE-416) - CVE-2021-32944The expected impact depends on each vulnerability, but it may be affected as follows. It was * crafted by the attacker DWG Denial of service by opening the file (DoS) triggering a condition or reading sensitive information from memory - CVE-2021-32938 It was * crafted by the attacker DXF Denial of service by opening files via recovery (DoS) state is triggered or code is executed - CVE-2021-32936 It was * crafted by the attacker DWG Denial of service by opening files via recovery (DoS) triggering a condition or reading sensitive information from memory - CVE-2021-32940 It was * crafted by the attacker DGN Denial of service by reading the file (DoS) state is triggered or code is executed - CVE-2021-32946 , CVE-2021-32952 It was * crafted by the attacker DWG Denial of service by opening the file (DoS) state is triggered or code is executed - CVE-2021-32948 It was * crafted by the attacker DXF Denial of service by opening the file (DoS) triggering a condition or reading sensitive information from memory - CVE-2021-32950 It was * Crafted by an attacker by an attacker DGN Denial of service by opening the file (DoS) A condition is triggered or arbitrary code is executed - CVE-2021-32944. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of DGN files. Pillow is a Python-based image processing library. \nThere is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements",
