Detailsinfo

A vulnerability was found in PointCloudLibrary pcl up to 1.14.x. It has been rated as critical. Affected by this issue is an unknown code of the file inftrees.c of the component zlib. The manipulation with an unknown input leads to a remote code execution vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is handled as CVE-2025-4638 since 05/13/2025. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 237486 (RHEL 7 : zlib (RHSA-2025:8314)), which helps to determine the existence of the flaw in a target environment.
