    Synopsis
    ========

    ProZilla contains several buffer overflow vulnerabilities that can be
    exploited by a malicious server to execute arbitrary code with the
    rights of the user running ProZilla.

    Background
    ==========

    ProZilla is a download accelerator for Linux.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 www-client/prozilla <= 1.3.6-r2 Vulnerable!
        -------------------------------------------------------------------
         NOTE: Certain packages are still vulnerable. Users should migrate
               to another package if one is available or wait for the
               existing packages to be marked stable by their
               architecture maintainers.

    Description
    ===========

    ProZilla contains several exploitable buffer overflows in the code
    handling the network protocols.

    Impact
    ======

    A remote attacker could setup a malicious server and entice a user to
    retrieve files from that server using ProZilla. This could lead to the
    execution of arbitrary code with the rights of the user running
    ProZilla.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    Currently, there is no released version of ProZilla that contains a fix
    for these issues. The original author did not respond to our queries,
    the code contains several other problems and more secure alternatives
    exist. Therefore, the ProZilla package has been hard-masked prior to
    complete removal from Portage, and current users are advised to unmerge
    the package.

    Availability
    ============

    This GLSA and any updates to it are available for viewing at
    the Gentoo Security Website:
