{"id":"CVE-2020-11105","details":"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.","modified":"2026-07-08T20:58:20.671424Z","published":"2020-03-30T22:15:15.180Z","related":["openSUSE-SU-2024:12197-1"],"references":[{"type":"EVIDENCE","url":"https://github.com/USCiLab/cereal/issues/636"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uscilab/cereal","events":[{"introduced":"0"},{"last_affected":"02eace19a99ce3cd564ca4e379753d69af08c2c8"}],"database_specific":{"cpe":"cpe:2.3:a:usc:cereal:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"last_affected":"1.3.0"}],"source":"CPE_RANGE"}}],"versions":["v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.2","v1.1.0","v1.0.0","v0.9.1","v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-11105.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
