CVE-2004-0078 in Mutt
Summary
by MITRE
Buffer overflow in the index menu code (menu_pad_string of menu.c) for Mutt 1.4.1 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via certain mail messages.

The vulnerability identified as CVE-2004-0078 represents a critical buffer overflow condition within the Mutt email client software version 1.4.1 and earlier. This flaw exists specifically within the index menu code, more precisely in the menu_pad_string function located in the menu.c source file. The buffer overflow occurs when processing certain mail messages that contain maliciously crafted data, creating a potential vector for remote exploitation.
The technical implementation of this vulnerability stems from insufficient input validation and boundary checking within the menu_pad_string function. When Mutt processes email messages containing specially crafted strings, the application fails to properly validate the length of input data before copying it into fixed-size buffers. This classic buffer overflow condition allows an attacker to overwrite adjacent memory locations, potentially leading to arbitrary code execution or system crashes. The vulnerability is particularly concerning because it can be triggered through normal email processing without requiring any special privileges or user interaction beyond receiving the malicious message.
From an operational perspective, this vulnerability creates significant risk for organizations relying on Mutt as their primary email client. The remote exploitation capability means that attackers can compromise systems simply by sending malicious emails, making it a highly attractive target for automated attacks. The denial of service aspect can result in complete system unavailability, while the potential for arbitrary code execution opens pathways for full system compromise. This vulnerability directly impacts the integrity and availability of email services, particularly affecting users who process untrusted mail content without proper sanitization measures.
The security implications of CVE-2004-0078 align with CWE-121, which categorizes buffer overflow conditions as a fundamental weakness in software design. The vulnerability also maps to ATT&CK technique T1059.007 for command and scripting interpreter, as successful exploitation could enable attackers to execute arbitrary commands on compromised systems. Organizations should implement immediate mitigations including upgrading to Mutt version 1.5.0 or later, which contains the necessary patches to address this buffer overflow. Additionally, deploying email filtering solutions that can detect and quarantine suspicious content, implementing strict input validation procedures, and establishing regular security updates for all email client software are essential defensive measures. The vulnerability demonstrates the critical importance of maintaining up-to-date software and proper input validation practices to prevent exploitation of memory corruption flaws that can lead to complete system compromise.
