Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.
2) Input validation error (CVE-ID: CVE-2022-3171)
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.
3) Out-of-bounds write (CVE-ID: CVE-2022-1304)
The vulnerability allows a local attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input. A local attacker can use a specially crafted filesystem, trigger out-of-bounds write and execute arbitrary code on the target system.
4) Improper Authorization (CVE-ID: CVE-2022-31692)
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to authorization rules bypass via forward or include dispatcher types. A remote attacker can bypass authorization process.
