Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2019-12399)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output within the Apache Kafka Connect REST API tasks endpoint. A remote authenticated user can issue a request to the same Connect cluster to obtain the connector's task configurations and the response will contain the plaintext secret.
2) Resource management error (CVE-ID: CVE-2019-12402)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the file name encoding algorithm can get into an infinite loop when faced with
specially crafted inputs. A remote attacker can choose the file names inside of an archive created by Compress and cause a denial of service condition on the target system.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2020-11979)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect patch for vulnerability #VU27924 (CVE-2020-1945). Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process.
