Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Incorrect default permissions (CVE-ID: CVE-2020-8908)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect default permissions for files located in the temporary directory set by the Guava com.google.common.io.Files.createTempDir(). A local user with access to the system can view contents of files and directories or modify them.


2) Resource management error (CVE-ID: CVE-2021-22883)

The 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 when processing multiple connection attempts with an 'unknownProtocol'. A remote attacker can initiate multiple connections with the server, which will trigger a leak of file descriptors and result in a denial of service (DoS) condition.


3) Resource exhaustion (CVE-ID: CVE-2020-11612)

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

The vulnerability exists due to application does not properly control consumption of internal resources within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.


4) Input validation error (CVE-ID: CVE-2020-13956)

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to insufficient validation of user-supplied input in Apache HttpClient. A remote attacker can pass request URIs to the library as java.net.URI object and force the application to pick the wrong target host for request execution.
