Source: symfony
Version: 4.4.4-1
Severity: grave
Tags: security upstream


The following vulnerabilities were published for symfony.

| In symfony/security-http before versions 4.4.7 and 5.0.7, when a
| `Firewall` checks access control rule, it iterate overs each rule's
| attributes and stops as soon as the accessDecisionManager decides to
| grant access on the attribute, preventing the check of next attributes
| that should have been take into account in an unanimous strategy. The
| accessDecisionManager is now called with all attributes at once,
| allowing the unanimous strategy being applied on each attribute. This
| issue is patched in versions 4.4.7 and 5.0.7.

| In Symfony before versions 5.0.5 and 4.4.5, some properties of the
| Exception were not properly escaped when the `ErrorHandler` rendered
| it stacktrace. In addition, the stacktrace were displayed even in a
| non-debug configuration. The ErrorHandler now escape alls properties
| of the exception, and the stacktrace is only display in debug
| configuration. This issue is patched in symfony/http-foundation
| versions 4.4.5 and 5.0.5

| In Symfony before versions 4.4.7 and 5.0.7, when a `Response` does not
| contain a `Content-Type` header, affected versions of Symfony can
| fallback to the format defined in the `Accept` header of the request,
| leading to a possible mismatch between the response's content
| and `Content-Type` header. When the response is cached, this can
| prevent the use of the website by other users. This has been patched
| in versions 4.4.7 and 5.0.7.
