Starting in version 0.5.0 and prior to version 0.12.0, an issue in the FamStructWrapperdeserialize implementation provided by the crate for vmmsysutilfamFamStructWrapper can lead to out of bounds memory accesses. The deserialization does not check that the length stored in the header matches the flexible array length. Mismatch in the lengths might allow out of bounds memory access through Rustsafe methods. The issue was corrected in version 0.12.0 by inserting a check that verifies the lengths of compared flexible arrays are equal for any deserialized header and aborting deserialization otherwise. Moreover, the API was changed so that header length can only be modified through Rustunsafe code. This ensures that users cannot trigger outofbounds memory access from Rustsafe code.\n\n\ud83d\udcd6 Read more\n\nVia \"National Vulnerability Database\"", "creation_timestamp": "2024-01-03T01:36:39.000000Z"}, {"uuid": "d702437d-0fd8-4126-9491-ad042ce357dd", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2023-50711", "type": "seen", "source": "https://t.me/ctinow/162026", "content": "https://ift.tt/8TL1q2A\nCVE-2023-50711", "creation_timestamp": "2024-01-02T21:26:17.000000Z"}, {"uuid": "f371d1bc-e081-47db-84ef-dfc79fb85c56", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2023-50711", "type": "seen", "source": "https://t.me/ctinow/171758", "content": "https://ift.tt/chUW2fs\nCVE-2023-50711 | vmm-sys-util prior 0.12.0 deserialization", "creation_timestamp": "2024-01-23T08:21:39.000000Z"}]}
