Description:
    Sebastian Krahmer from the SuSE Security Team discovered [1] a flaw
    in Concurrent Versions System (CVS) [0] clients where RCS "diff
    files" can create files with absolute pathnames. An attacker could
    create a fake malicious CVS server that would cause arbitrary files
    to be created or overwritten when a victim connects to it.
