ruby: NUL injection vulnerability of File.fnmatch and File.fnmatch?

A flaw was discovered in Ruby in the way certain functions handled strings containing NULL bytes. Specifically, the built-in methods File.fnmatch and its alias File.fnmatch? did not properly handle path patterns containing the NULL byte. A remote attacker could exploit this flaw to make a Ruby...

CVE-2021-29492 Bypass of path matching rules using escaped slash characters

Envoy is a cloud-native edge/middle/service proxy. Envoy does not decode escaped slash sequences %2F and %5C in HTTP URL paths in versions 1.18.2 and before. A remote attacker may craft a path with escaped slashes, e.g. /something%2F..%2Fadmin, to bypass access control, e.g. a block on /admin. A...
