This issue may allow context-dependent attackers to cause undefined behavior by exploiting improper pointer arithmetic.\n\nSince 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.\n\ud83d\udccf Published: 2025-05-14T17:59:58.180Z\n\ud83d\udccf Modified: 2025-05-14T17:59:58.180Z\n\ud83d\udd17 References:\n1. https://github.com/PointCloudLibrary/pcl/pull/6245\n2. https://github.com/PointCloudLibrary/pcl/blob/master/surface/CMakeLists.txt#L70\n3. https://github.com/PointCloudLibrary/pcl/commit/502bd2b013ce635f21632d523aa8cf2e04f7b7ac", "creation_timestamp": "2025-05-14T18:32:13.000000Z"}
