Augeas · Augeas · CVE-2013-6412
**Name of the Vulnerable Software and Affected Versions**
Augeas versions 1.0.0 through 1.1.0
**Description**
The issue is related to the `transform save` function in `transform.c` which does not properly calculate permission values when the umask contains a "7". This causes world-writable permissions to be used for new files, allowing local users to modify the files. The exploitation of this issue can lead to a violation of confidentiality, integrity, and availability of protected information. It can be exploited locally.
**Recommendations**
For Augeas versions 1.0.0 through 1.1.0, consider updating to a version where the `transform save` function is properly fixed to handle permission values correctly. As a temporary workaround, restrict access to files created by the `transform save` function to minimize the risk of exploitation. Avoid using the `umask` with a value containing "7" in the affected versions until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
