AlienVault OTX Vulnerabilities

AlienVault OTX Malware

An issue was found in the tiffcp utility distributed by the libtiff package where a crafted TIFF file on processing may cause a heap-based buffer overflow leads to an application crash.

CVE-2023-6228 is a heap-based buffer overflow vulnerability identified in the tiffcp utility, which is part of the libtiff package distributed with Red Hat Enterprise Linux 8. The vulnerability arises when tiffcp processes a specially crafted TIFF file, causing an out-of-bounds write on the heap. This memory corruption leads to an application crash, resulting in a denial of service condition. The vulnerability does not impact confidentiality or integrity, as it does not allow code execution or data leakage. Exploitation requires local access to the system, no privileges are needed, but user interaction is necessary to trigger the vulnerability by processing the malicious TIFF file. The CVSS v3.1 base score is 3.3, reflecting low severity due to the limited scope and impact. No known exploits have been reported in the wild, and no patches were linked at the time of the report, though Red Hat typically issues updates promptly. The vulnerability affects Red Hat Enterprise Linux 8 systems that include the vulnerable libtiff version and use the tiffcp utility for TIFF file manipulation. This utility is commonly used in image processing workflows, automated scripts, or batch processing environments. An attacker with local access could cause denial of service by crashing applications or services relying on tiffcp, potentially disrupting operations that depend on TIFF file handling.
