The remote host is affected by the vulnerability described in GLSA-200410-25 (Netatalk: Insecure tempfile handling in etc2ps.sh)
The etc2ps.sh script creates temporary files in world-writeable directories with predictable names.
Impact :
A local attacker could create symbolic links in the temporary files directory, pointing to a valid file somewhere on the filesystem. When etc2ps.sh is executed, this would result in the file being overwritten with the rights of the user running the utility, which could be the root user.
Workaround :
There is no known workaround at this time.
