Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Resource management error
EUVDB-ID: #VU60181
Risk: Medium
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2021-22569
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application. protobuf-java allowes the interleaving of
com.google.protobuf.UnknownFieldSet fields in such a way that would be
processed out of order. A small malicious payload can occupy the parser
for several minutes by creating large numbers of short-lived objects
that cause frequent, repeated pauses. A remote attacker can trick the victim into passing specially crafted data to the application and perform a denial of service attack.
Update the affected package protobuf to the latest version.
