affected: Framework Bundle, Dependency Injection, Security,

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-ar
e-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-remembe
r-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-ove
rrides

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.
