Descriptions

A flaw was found in curl before version 7.51. If cookie state is written into a cookie jar file that is later read back and used for subsequent requests, a malicious HTTP server can inject new cookies for arbitrary domains into said cookie jar.

Se ha descubierto un problema en versiones anteriores a la 7.51 de curl. Si se escribe el estado de la cookie en un archivo jar de cookie que, posteriormente, será leído y empleado para futuras peticiones, un servidor HTTP malicioso puede inyectar nuevas cookies para dominios arbitrarios en ese jar cookie.

It was discovered that curl incorrectly reused client certificates when built with NSS. A remote attacker could possibly use this issue to hijack the authentication of a TLS connection. Nguyen Vu Hoang discovered that curl incorrectly handled escaping certain strings. A remote attacker could possibly use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. Various other issues were also addressed.
