CVE-2005-3178 in xli
Summary
by MITRE
Buffer overflow in xloadimage 4.1 and earlier, and xli, might allow user-assisted attackers to execute arbitrary code via a long title name in a NIFF file, which triggers the overflow during (1) zoom, (2) reduce, or (3) rotate operations.

The vulnerability identified as CVE-2005-3178 represents a critical buffer overflow flaw affecting xloadimage version 4.1 and earlier, as well as the xli utility. This security issue stems from inadequate input validation within the image processing routines that handle NIFF file formats. The vulnerability manifests when users attempt to perform basic image operations such as zoom, reduce, or rotate on specially crafted NIFF files containing excessively long title names. The flaw operates at the intersection of memory management and file format parsing, creating a condition where the application fails to properly bounds-check string inputs during image manipulation processes. The vulnerability is classified under CWE-121 as a stack-based buffer overflow, which occurs when a program writes more data to a fixed-length buffer than it can accommodate, leading to memory corruption that can be exploited by malicious actors.
The operational impact of this vulnerability extends beyond simple denial of service scenarios, as it provides attackers with the potential to execute arbitrary code with the privileges of the affected user. When a user opens a maliciously crafted NIFF file through xloadimage or xli, the application's buffer overflow condition can be triggered during the specified image operations, allowing attackers to overwrite adjacent memory locations. This type of vulnerability aligns with ATT&CK technique T1203, which involves the exploitation of input validation flaws to achieve code execution. The attack vector is user-assisted, meaning that victims must intentionally open the malicious file, but the potential for exploitation remains high given the privilege escalation opportunities available through the buffer overflow. The vulnerability affects systems where these image viewing utilities are installed and actively used, particularly in environments where users may encounter untrusted image files.
Mitigation strategies for CVE-2005-3178 should focus on both immediate remediation and long-term security hardening approaches. The most effective immediate solution involves upgrading to patched versions of xloadimage and xli, as the vulnerability was addressed in subsequent releases that implemented proper input validation and bounds checking. System administrators should also consider implementing restrictive file access controls and user permissions to limit the execution of potentially malicious image files. Additionally, deploying security tools such as address space layout randomization and stack canaries can help mitigate exploitation attempts, though these measures are considered defensive rather than primary fixes. The vulnerability demonstrates the importance of input validation in image processing libraries and highlights the need for robust memory safety practices in legacy software systems. Organizations should also consider implementing network segmentation and file scanning mechanisms to prevent the accidental execution of malicious image files, particularly in environments where users may encounter untrusted content. This vulnerability serves as a reminder of the critical importance of maintaining up-to-date software versions and implementing comprehensive security controls for multimedia processing applications.
