    descriptionThe etc2ps.sh script, part of the netatalk package, creates files in /tmp with predicatable names which could allow a local attacker to use symbolic links to point to a valid file on the filesystem which could lead to the overwriting of arbitrary files if etc2ps.sh is executed by someone with enough privilege. The updated packages are patched to prevent this problem.

    descriptionThe 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.
