Описание
Use of Java's default temporary directory for file creation in FileBackedOutputStream in Google Guava versions 1.0 to 31.1 on Unix systems and Android Ice Cream Sandwich allows other users and apps on the machine with access to the default Java temporary directory to be able to access the files created by the class.
Even though the security vulnerability is fixed in version 32.0.0, we recommend using version 32.0.1 as version 32.0.0 breaks some functionality under Windows.
A flaw was found in Guava. The methodology for temporary directories and files can allow other local users or apps with accordant permissions to access the temp files, possibly leading to information exposure or tampering in the files created in the directory.
Отчет
Red Hat Single Sign-On 7 ships the affected component as a layered product of Red Hat JBoss Enterprise Application 7, and as such is affected by this flaw. However, Single Sign-On 7 does not use the affected code and is not vulnerable to exploit.
Меры по смягчению последствий
Temp files should be created with sufficiently non-predictable names and in a secure-permissioned, dedicated temp folder.
