Description

This security bulletin contains information about 2 vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2021-22904)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a use-after-free error in the Token Authentication logic in Action Controller. A remote attacker can send a specially crafted request and cause a denial of service condition on the target system. 


2) Information disclosure (CVE-ID: CVE-2022-23633)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists in the Rack middleware package of RubyGems, where response bodies will not close under certain circumstances. A remote attacker can iterate requests to force ActionDispatch::Executor to not close, allowing subsequent requests to leak data from ActiveSupport::CurrentAttributes.
