Does this matter?

Lower severity and a low EPSS score (2.03%). Track it; it rarely justifies an emergency change on its own.

Description

Format string bug in the open_altfile function in filename.c for GNU less 382, 381, and 358 might allow local users to cause a denial of service or possibly execute arbitrary code via format strings in the LESSOPEN environment variable. NOTE: since less is not setuid or setgid, then this is not a vulnerability unless there are plausible scenarios under which privilege boundaries could be crossed
