6.4 MEDIUM — AV:N/AC:L/Au:N/C:N/I:P/A:P

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

Affected configurations

• gnu less 358 • gnu less 381 • gnu less 382
