发布于3月6日3月6日 Members CentOS Linux: CVE-2022-43552: Low: curl security update (CESA-2023:7743) Severity 7 CVSS (AV:N/AC:M/Au:N/C:N/I:N/A:C) Published 02/09/2023 Created 05/15/2023 Added 05/15/2023 Modified 01/28/2025 Description A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path.
