Priority reason: no security impact as terminfo files are trusted |
|
| mdeslaur | This is in the code that parses terminfo database files. terminfo files are normally trusted, and since the fix for CVE-2023-29491, we no longer parse terminfo files when apps are setuid. As such, this doesn't really have a security impact. Setting priority to low. |
