Wire Swift runtime: negative LENGTH_DELIMITED length in skipGroup() crashes any protobuf-decoding service

Summary Wire's Swift runtime Wire SPM/CocoaPods product, implemented by wire-runtime-swift did not reject a negative LENGTHDELIMITED field length while skipping an unknown protobuf group. A crafted 10-byte protobuf payload could cause ProtoReader.skipGroup to read a length-delimited field whose...

Improper Validation of Array Index

Overview Affected versions of this package are vulnerable to Improper Validation of Array Index in the skipGroup function. An attacker can cause a service crash by sending a crafted protobuf payload with a negative length in a length-delimited field inside a group, leading to an unchecked runtime...
