Overview

CVE-2020-11105 is a critical-severity vulnerability. It was published on March 30, 2020 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

An issue was discovered in USC iLab cereal through 1.3.0. It employs caching of std::shared_ptr values, using the raw pointer address as a unique identifier. This becomes problematic if an std::shared_ptr variable goes out of scope and is freed, and a new std::shared_ptr is allocated at the same address. Serialization fidelity thereby becomes dependent upon memory layout. In short, serialized std::shared_ptr variables cannot always be expected to serialize back into their original values. This can have any number of consequences, depending on the context within which this manifests.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
