CVE-2025-4638 – PCL Zlib Inftrees Pointer Arithmetic Vulnerability

CVE ID : CVE-2025-4638

Published : May 14, 2025, 6:15 p.m. | 39 minutes ago

Description : 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: 0.0 | NA
