    Package        : flex
    Vulnerability  : buffer overflow
    Problem-Type   : local
    Debian-specific: no
    CVE ID         : CVE-2006-0459
    Chris Moore discovered that flex, a scanner generator, generates code,
    which allocates insufficient memory, if the grammar contains REJECT
    statements or trailing context rules. This may lead to a buffer overflow
    and the execution of arbitrary code.
    If you use code, which is derived from a vulnerable lex grammar in
    an untrusted environment you need to regenerate your scanner with the
    fixed version of flex.
    The old stable distribution (woody) is not affected by this problem.
    For the stable distribution (sarge) this problem has been fixed in
    version 2.5.31-31sarge1.
    For the unstable distribution (sid) this problem has been fixed in
    version 2.5.33-1.
    We recommend that you upgrade your flex package.
