CVE-2020-5275 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream symfony package and not the symfony package as distributed by Debian.
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.
