Comment 1 Alexander Bergmann 2023-08-23 07:46:29 UTC

Note: Do not trust data from unknown sources. Do not disassemble binaries from unknown sources without a sandbox environment that protects you from possible attacks.

In general: This is not a severe issue. It can only exploited if general security measurements and best practices are not followed.

For now, we will keep this bug open for reference. 

Current status:
- Error is only directly visible via AddressSanitizer.
- No upstream fix available.
