CVE-2021-27496 (GCVE-0-2021-27496)

Vulnerability from cvelistv5 – Published: 2021-05-27 15:27 – Updated: 2024-08-03 21:26
VLAI
Summary
Datakit Software libraries CatiaV5_3dRead, CatiaV6_3dRead, Step3dRead, Ug3dReadPsr, Jt3dReadPsr modules in KeyShot Versions v10.1 and prior lack proper validation of user-supplied data when parsing PRT files. This could lead to pointer dereferences of a value obtained from an untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process.
Severity
No CVSS data available.

CVE-2021-31481 (GCVE-0-2021-31481)

Vulnerability from cvelistv5 – Published: 2021-06-15 19:11 – Updated: 2024-08-03 23:03
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of OpenText Brava! Desktop 16.6.3.84. 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 SLDPRT files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12659.
Severity

Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of OpenText Brava! Desktop Build 16.6.3.84 (package 16.6.3.134). 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 PDF files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-12691.

CAPEC-129: Pointer Manipulation

This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
