CVSS: 8.1EPSS: 10%CPEs: 40EXPL: 2CVE-2021-22901 – curl: Use-after-free in TLS session handling when using OpenSSL TLS backend
https://notcve.org/view.php?id=CVE-2021-22901
curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives. If the connection is used by multiple transfers (like with a reused HTTP/1.1 connection or multiplexed HTTP/2 connection) that first transfer object might be freed before the new session is established on that connection and then the function will access a memory buffer that might be freed. When using that memory, libcurl might even call a function pointer in the object, making it possible for a remote code execution if the server could somehow manage to get crafted memory content into the correct place in memory. curl versiones 7.75.0 hasta 7.76.1 sufre de una vulnerabilidad de uso de la memoria previamente liberada que resulta en el uso de memoria ya liberada cuando un ticket de sesión TLS 1.3 llega a través de una conexión. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-732250.pdf https://curl.se/docs/CVE-2021-22901.html https://github.com/curl/curl/commit/7f4a9a9b2a49547eae24d2e19bc5c346e9026479 https://hackerone.com/reports/1180380 https://security.netapp.com/advisory/ntap-20210723-0001 https://security.netapp.com/advisory/ntap-20210727-0007 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022. • CWE-416: Use After Free •
