Vulnerability from github – Published: 2025-05-14 18:30 – Updated: 2025-10-21 15:30

Details

Since version 1.14.0, PCL by default uses a zlib installation from the system, unless the user sets WITH_SYSTEM_ZLIB=FALSE. So this potential vulnerability is only relevant if the PCL version is older than 1.14.0 or the user specifically requests to not use the system zlib.

Severity

9.8 (Critical)

CVE-2025-4638 (GCVE-0-2025-4638)

Vulnerability from cvelistv5 – Published: 2025-05-14 17:59 – Updated: 2025-05-15 13:49

Title

Improper Pointer Arithmetic in pcl

Summary

A vulnerability exists in the inftrees.c component of the zlib library, which is bundled within the PointCloudLibrary (PCL). This issue may allow context-dependent attackers to cause undefined behavior by exploiting improper pointer arithmetic. Since version 1.14.0, PCL by default uses a zlib installation from the system, unless the user sets WITH_SYSTEM_ZLIB=FALSE. So this potential vulnerability is only relevant if the PCL version is older than 1.14.0 or the user specifically requests to not use the system zlib.

Severity

9.2 (Critical)
