CVE-2007-2758 in WinImage
Summary
by MITRE
Multiple buffer overflows in WinImage 8.0.8000 allow user-assisted remote attackers to execute arbitrary code via a FAT image that contains long directory names in a deeply nested directory structure, which triggers (1) a stack-based buffer overflow during extraction, or (2) a heap-based buffer overflow during traversal.

The vulnerability identified as CVE-2007-2758 represents a critical security flaw in WinImage 8.0.8000 that exposes users to remote code execution risks through malformed FAT image files. This issue stems from inadequate input validation and memory management practices within the software's handling of directory structures, creating exploitable conditions that can be triggered by specially crafted archive files. The vulnerability affects the software's ability to process deeply nested directory hierarchies with excessively long directory names, which are common in various file compression and archiving formats.
The technical implementation of this vulnerability manifests through two distinct buffer overflow conditions that exploit different memory management patterns. The first condition creates a stack-based buffer overflow during the extraction process when processing directory names that exceed allocated buffer boundaries, while the second condition generates a heap-based buffer overflow during directory traversal operations. Both scenarios occur when WinImage encounters FAT images containing deeply nested directory structures with directory names that surpass predetermined length limits, causing memory corruption that can be leveraged by malicious actors.
From an operational perspective, this vulnerability presents significant risks to organizations relying on WinImage for file management and archiving operations. The user-assisted nature of the attack means that victims must interact with maliciously crafted FAT images, typically through email attachments or file sharing platforms, making social engineering components essential for successful exploitation. The remote execution capability allows attackers to potentially gain full system control without requiring local access, making this vulnerability particularly dangerous in enterprise environments where file sharing and archiving systems are prevalent.
The underlying flaw aligns with common software security weaknesses categorized under CWE-121, which addresses stack-based buffer overflow conditions, and CWE-122, which covers heap-based buffer overflow scenarios. These classifications indicate fundamental issues in memory management and input validation that are frequently exploited in real-world attacks. The vulnerability also maps to ATT&CK technique T1059.007, which involves the use of scripting languages for execution, as attackers can leverage the buffer overflow conditions to inject and execute malicious code within the target system's memory space.
Mitigation strategies for CVE-2007-2758 should prioritize immediate software updates and patches from the vendor, as well as network-level restrictions on file types that could contain malicious FAT images. Organizations should implement strict file validation policies that reject or quarantine suspicious archive files, particularly those originating from untrusted sources. Network segmentation and endpoint protection measures can help prevent exploitation attempts from spreading throughout the organization. Additionally, regular security assessments should verify that all systems using WinImage or similar archiving software have been properly patched and that appropriate monitoring controls are in place to detect potential exploitation attempts.
