发布于3月6日3月6日 Members Amazon Linux AMI 2: CVE-2023-27537: Security patch for curl (ALAS-2023-2070) Severity 7 CVSS (AV:N/AC:M/Au:N/C:N/I:N/A:C) Published 03/30/2023 Created 06/08/2023 Added 06/08/2023 Modified 01/30/2025 Description A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free.
