[ECHO_ADV_42$2006] BufferOverflow in Eremove Client

Author : Dedi Dwianto Date : Aug, 01st 2006 Location : Indonesia, Jakarta Web : http://advisories.echo.or.id/adv/adv42-theday-2006.txt Exploitation : Local Critical Lvl : High


Affected software description: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Application : Eremove version : 1.4 URL : http://eremove.sourceforge.net/ Description : Eremove is a simple application for linux, based on GTK, for logging into a POP3 mail account, quickly seeing a summary of everything that is there waiting for you, and previewing/deleteing some or all of those emails painlessly.


Vulnerability: ~~~~~~~~~~~~~~~~ The function priview_create used by Eremove is affected by a buffer-overflow vulnerability which happens when it tries to store the exceeding data available in the input email in the message_body buffer of only 65534 bytes.

------------------gui.cpp----------------------------- ..... gint preview_create (int message_num) { ... GtkWidget hbox; GtkWidget vscrollbar; char tmp_pntr; char tmp_str[255]; char buf[65534]; char message_body[65534]; gint i; ... } if (!find_header_field("Date", buf, &date)) { date = (char ) malloc(strlen("unspecified")*sizeof(char)); strcpy(date, "unspecified"); } strcpy(message_body, buf); ... ----------------------------------------------------------

POC: ~~~~ Send EMail with Attachment more than 100 KB and Openwith eremove. Eremove will be crash.
