On Windows, The IsLocal function does not correctly detect reserved device
names in some cases. Reserved names followed by spaces, such as "COM1 ",
and reserved names โ€œCOMโ€ and โ€œLPTโ€ followed by superscript 1, 2, or 3, are
incorrectly reported as local. With fix, IsLocal now correctly reports
these names as non-local.

Notes

Author Note
mdeslaur Packages built using golang need to be rebuilt once the vulnerability has been fixed. This CVE entry does not list packages that need rebuilding outside of the main repository or the Ubuntu variants with PPA overlays.
rodrigo-zaiden may impact only Windows paths, a better triage of real impact, if any, is appreciated. closed related to CVE-2023-45283
