4 | Security Fixes
The Advanced tab is removed from Amanda Enterprise 3.6 to prevent security flaws.
Security issues that were fixed in Amanda Community for this release:
1. The patch for CVE-2016-10729 issue used WHITELIST approach to filter the tar arguments for runtar application. During the same time options filtering implementation was done for amgtar, amstar and ambsdtar. But those changes were done using the BLACKLIST approach. And hence option “-F” for amgtar application can be used to get the data that should only be allowed by root user. The similar issue was present with amstar application.
2. The same approach was taken with “rundump” application for exploiting the security issue. “rundump” application was not doing any option filtering.
/usr/lib/amanda/rundump NOCONFIG xfsdump -0f /dev/null /sys -F "echo test"
It was working fine when the command is provided like mentioned:
/usr/lib/amanda/rundump NOCONFIG xfsdump -0f /dev/null -F "echo test" /sys
