Description Josh Bressers 2010-09-15 17:26:58 UTC

thttpd 2.25b0 writes data to a log file without sanitizing non-printable
characters, which might allow remote attackers to modify a window's title,
or possibly execute arbitrary commands or overwrite files, via an HTTP
request containing an escape sequence for a terminal emulator.

There is no upstream patch for this flaw I can find. Upstream seems pretty
slow.
