Description :

The remote host is affected by the vulnerability described in GLSA-200803-23

Temporary files are handled insecurely in the files

wml_backend/p3_eperl/eperl_sys.c, allowing users to overwrite or delete
arbitrary files with the privileges of the user running the program.

symlink attacks to perform certain actions with escalated privileges.

Workaround :

Restrict access to the temporary directory to trusted users only.
