Numerous symfony components are affected: Framework Bundle, Dependency Injection, Security, HttpFoundation CVE-2019-10909 Validation messages were not escaped when using the form theme of the PHP templating engine which, when validation messages may contain user input, could result in an XSS. For further information, see the upstream advisory at https://symfony.com/blog/cve-2019-10909-escape-validation-messages-in-the-php-templating-engine CVE-2019-10910 Service IDs derived from unfiltered user input could result in the execution of any arbitrary code, resulting in possible remote code execution. For further information, see the upstream advisory at https://symfony.com/blog/cve-2019-10910-check-service-ids-are-valid CVE-2019-10911 This fixes situations where part of an expiry time in a cookie could be considered part of the username, or part of the username could be considered part of the expiry time. An attacker could modify the remember me cookie and authenticate as a different user. This attack is only possible if remember me functionality is enabled and the two users share a password hash or the password hashes (e.g. UserInterface::getPassword()) are null for all users (which is valid if passwords are checked by an external system, e.g. an SSO). For further information, see the upstream advisory at https://symfony.com/blog/cve-2019-10911-add-a-separator-in-the-remember-me-cookie-hash CVE-2019-10913 HTTP methods, from either the HTTP method itself or using the X-Http-Method-Override header were previously returned as the method in question without validation being done on the string, meaning that they could be used in dangerous contexts when left unescaped. For further information, see the upstream advisory at https://symfony.com/blog/cve-2019-10913-reject-invalid-http-method-overrides For Debian 8 "Jessie", these problems have been fixed in version 2.3.21+dfsg-4+deb8u5. We recommend that you upgrade your symfony packages.
