2) Input validation error

EUVDB-ID: #VU69293

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3171

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.
