CVE-2021-27496: (0Day) Siemens Solid Edge Viewer PRT File Parsing Untrusted Pointer Dereference Remote Code Execution Vulnerability
First published: Thu May 27 2021(Updated: )
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.
