CVE-2024-7254

Severity CVSS v4.0:
HIGH
Type:
CWE-400 Uncontrolled Resource Consumption ('Resource Exhaustion')
Publication date:
19/09/2024
Last modified:

Description

Any project that parses untrusted Protocol Buffers data containing an arbitrary number of nested groups / series of SGROUP tags can corrupted by exceeding the stack limit i.e. StackOverflow. Parsing nested groups as unknown fields with DiscardUnknownFieldsParser or Java Protobuf Lite parser, or against Protobuf map fields, creates unbounded recursions that can be abused by an attacker.
