(Reuters) - Intel Corp <INTC.O>, which is rushing to fix recently disclosed security flaws in its chips, reported a 4.1 percent rise in quarterly revenue, helped by strong growth in its data center business.


The company reported a loss of $687 million, or 15 cents per share, in the fourth quarter ended Dec. 30, due to an income tax expense of $5.4 billion as a result of the recent tax reforms.


The company had posted a profit of $3.56 billion, or 75 cents per share, a year earlier.


Total revenue rose to $17.05 billion from $16.37 billion.


Intel's shares were up 4.3 percent in extended trading.
