Description Lubomir Kundrak 2007-04-05 12:28:40 EDT
Description of problem:

Arnaud Giersch discovered that the following chunk of code from
src/intl/gettext/loadmsgcat.c:add_filename_to_string() causes elinks
to read .po files fro man untrusted location.

215         if ((dirnamelen && !add_bytes_to_string(str, program.path, dirnamelen))
216             || !add_to_string(str, "../po/")
217             || !add_bytes_to_string(str,

An untrusted message catalog might lead to a format-string attack when an
attacker tricks user into launching links from a particular directory.

Version-Release number of selected component (if applicable):

        Doesn't Affect: RHEL3
        Affects: RHEL4
        Affects: RHEL5
        Affects: FC5
        Affects: FC6

Additional info:

It is questionable who would launch elinks from a directory controlled
by someone else and thus whether this is exploitable in real world.

Upstream patches:

These patches were questioned in the debian bug, however it seems like doubts
were unreasonable.
