CVE-2016-2366
A denial of service vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could potentially result in an out-of-bounds read. A malicious server or an attacker who intercepts the network traffic can send invalid data to trigger this vulnerability and cause a crash.
5.9 CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Pidgin 2.10.11
In the function command_table in mxit/formcmds.c at lines 531 and 535, the number of rows and columns for the table are received from the server.
531 nr_columns = atoi(tmp);
..
535 nr_rows = atoi(tmp);
These two values are then used in loops at line 547 and 548 and to access an array at line 549.
547 for (i = 0; i < nr_rows; i++) {
for (j = 0; j < nr_columns; j++) {
549 purple_debug_info(MXIT_PLUGIN_ID, " Row %i Column %i = %s\n", i, j, coldata[i*nr_columns + j]);
}
}
An attacker can cause access to unmapped memory addresses, resulting in a denial of service.
