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.
