Package: markdown Version: 1.0.1-10.1 Severity: important markdown(1) does various funny things if a filename contains characters that are not usually used in filenames:
$ echo a > '>t0' $ ls -l total 4 -rw-rw-r-- 1 zefram zefram 2 Jul 16 23:20 '>t0' $ markdown '>t0' $ ls -l total 4 -rw-rw-r-- 1 zefram zefram 2 Jul 16 23:20 '>t0' -rw-rw-r-- 1 zefram zefram 0 Jul 16 23:20 t0 $ echo b > 't1 ' $ markdown 't1 ' Can't open t1 : No such file or directory at /usr/bin/markdown line 221. $ These arise from its use of the <> Perl operator, which is not suitable for the implementation of a read-from-list-of-files kind of command. Because the range of misbehaviour includes writing to arbitrary files and running arbitrary commands, this is a more severe bug than normal. -zefram
