Caldera Advisory: rsync supplementary groups
| Caldera Advisory: rsync supplementary groups
|
1. Problem Description
Supplementary groups to which the rsync daemon belongs (such as
root) were not removed from the server process before it performed
work as an unprivileged uid and gid. The rsync daemon was also
compiled with a vulnerable version of the zlib library. This
package corrects both these issues.
2. Vulnerable Supported Versions
