The remote host is affected by the vulnerability described in GLSA-200411-15 (OpenSSL, Groff: Insecure tempfile handling)
groffer and the der_chop script create 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 groffer or der_chop 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.
