curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly. curl versiones 7.61.0 hasta 7.76.1, sufre de exposición de un elemento de datos a una sesión equivocada debido a un error en el código para la función CURLOPT_SSL_CIPHER_LIST cuando libcurl es construído para usar la biblioteca TLS de Schannel. El ajuste de cifrado seleccionado se almacenaba en una única variable "static" en la biblioteca, lo que tiene el sorprendente efecto secundario de que si una aplicación establece múltiples transferencias concurrentes, la última que ajusta los cifrados controlará accidentalmente el ajuste usado por todas las transferencias.

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 •

curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. curl versiones 7.7 hasta 7.76.1 sufre de una divulgacion de información cuando la opción de línea de comandos "-t", conocida como "CURLOPT_TELNETOPTIONS" en libcurl, se usa para enviar pares de variables=contenido a servidores TELNET.
