Some Linux distributions ship with BSD mailx 8.1.1-10 (On Slackware 7.x it can be found as /usr/bin/Mail).
|
|
|
|
A vulnerability exists in the 'mail' program, part of the Berkeley mailx package. The 'mail' program contains a buffer overflow condition that is present when the -c parameter is used at the command line.
|
|
|
|
On systems where it is installed setgid, this vulnerability can be exploited to gain group 'mail' privileges.

* mail-slak.c (C) 2000 Paulo Ribeiro <prrar@nitnet.com.br>
|
|
*
|
|
* Exploit for /usr/bin/Mail.
|
|
* Made specially for Slackware Linux 7.0.
|
|
* Based on mailx.c by funkySh.

|
|
* OBS.: Without fprintf(stderr) is not possible to print the message.
