CVE-2025-4638: Pointclouds Point Cloud Library

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Pointclouds Point Cloud Library: before 1.14.0 (fixed in 1.14.0)
