CWE-416

Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Vulnerability from cvelistv5

Severity ?
6.9 (Medium) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N
CWE
Summary
AUTOMGEN versions up to and including 8.0.0.7 (also referenced as 8.022) contain a vulnerability in that project file handling frees an object and subsequently dereferences the stale pointer when processing certain malformed fields. The dangling-pointer use enables an attacker to influence an indirect call through attacker-controlled memory, resulting in denial-of-service. In some conditions, remote code execution may be possible.
