Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200803-23
(Website META Language: Insecure temporary file usage)

Temporary files are handled insecurely in the files
wml_backend/p1_ipp/ipp.src, wml_contrib/wmg.cgi, and
wml_backend/p3_eperl/eperl_sys.c, allowing users to overwrite or delete
arbitrary files with the privileges of the user running the program.

Impact :

Local users can exploit the insecure temporary file vulnerabilities via
symlink attacks to perform certain actions with escalated privileges.

Workaround :

Restrict access to the temporary directory to trusted users only.
