4 | Security Fixes
The Advanced tab is removed from Amanda Enterprise 3.6 to prevent security flaws.
Security issues that are 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 the root user. The similar issue was present with amstar application.
- Fixes added to filter the WHITELIST options for amgtar and amstar applications.
- Filtered star arguments with WHITELIST approach.
- Filtered dump and xfsdump arguments with WHITELIST approach.
2. The same approach was taken with “rundump” application for exploiting the security issue, “rundump” application was not doing any option filtering.
- Fixes added to filter command argument with WHITELIST approach.
- In command below, "-F" is a blacklisted option. But providing command option like specified below was not filtering the options.
It was working fine when the command was provided like mentioned:
/usr/lib/amanda/rundump NOCONFIG xfsdump -0f /dev/null -F "echo test" /sys
