AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A null pointer dereference issue was found in Libtiff's tif_dir.c file. This issue may allow an attacker to pass a crafted TIFF image file to the tiffcp utility which triggers a runtime error that causes undefined behavior. This will result in an application crash, eventually leading to a denial of service.

CVE-2023-2908 identifies a null pointer dereference vulnerability within the Libtiff library, specifically in the tif_dir.c source file. This flaw manifests when the tiffcp utility processes a maliciously crafted TIFF image file, leading to a runtime error that dereferences a null pointer. The consequence is undefined behavior culminating in an application crash, effectively causing a denial of service (DoS) condition. The vulnerability is characterized by a CVSS v3.1 score of 5.5 (medium severity), with an attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope remains unchanged (S:U), and the impact affects availability only (A:H), with no confidentiality or integrity loss. No affected versions are explicitly listed, and no patches or known exploits have been reported at the time of publication. The flaw primarily threatens applications or systems that utilize Libtiff's tiffcp utility to handle TIFF images, especially when processing untrusted or external image files. The vulnerability does not allow remote code execution or privilege escalation but can disrupt service availability by crashing the application. This can impact workflows relying on image conversion or manipulation, potentially affecting automated systems or user-facing services that depend on Libtiff.
