    Bernhard R. Link discovered that the CVS browsing interface of Gforge, a
    collaborative development tool, performs insufficient escaping of URLs,
    which allows the execution of arbitrary shell commands with the privileges
    of the www-data user.
    
    The oldstable distribution (sarge) is not affected by this problem.
    
    For the stable distribution (etch) this problem has been fixed in
    version 4.5.14-5.
    
    For the unstable distribution (sid) this problem has been fixed in
    version 4.5.14-6.
    
    We recommend that you upgrade your gforge-plugin-scmcvs package.
    
    
    Upgrade Instructions
