A flaw has been found in LibTIFF 4.7.0. This affects the function _TIFFmallocExt/_TIFFCheckRealloc/TIFFHashSetNew/InitCCITTFax3 of the file tools/tiffcmp.c of the component tiffcmp. Executing manipulation can lead to memory leak. The attack is restricted to local execution. This attack is characterized by high complexity. It is indicated that the exploitability is difficult. The exploit has been published and may be used. There is ongoing doubt regarding the real existence of this vulnerability. This patch is called ed141286a37f6e5ddafb5069347ff5d587e7a4e0. It is best practice to apply a patch to resolve this issue. A researcher disputes the security impact of this issue, because "this is a memory leak on a command line tool that is about to exit anyway". In the reply the project maintainer declares this issue as "a simple 'bug' when leaving the command line tool and (...) not a security issue at all".

Security Impact Summary

This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 2.5, requiring local system access to exploit but requires specific conditions to be met without requiring user interaction requiring only low-level privileges .

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For libtiff's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
