Microsoft says security patches slowing down PCs, servers

(Reuters) - Corp said on Tuesday that released to guard against microchip security threats slowed down some personal computers and servers, with systems running on older Corp processors seeing a noticeable decrease in performance.

The comments in a blog post were the clearest signal from that fixes for flaws in from and rivals described last week could meaningfully degrade performance. The topic is of keen interest to large data centre operators, which could incur significant cost increases if computers slow down.

also said that security updates froze some computers using chipsets from rival , dragging AMD's shares down nearly 4 percent.

Shares in Intel, which reiterated on Tuesday that it saw no sign of significant slowdown in computers, fell 2.5 percent taking the loss since the issue surfaced last week to about 7 percent or around $15 billion in market value.

shares have gained nearly 20 percent in the last week as investors speculated that the chipmaker could wrest market share from Intel, whose chips were most exposed to the security flaws.

Security researchers disclosed the flaws on Jan. 3 that affected nearly every modern from Intel, and ARM Holdings, owned by Japan's <9984. T>.

"We (and others in the industry) had learned of this vulnerability under nondisclosure agreement several months ago and immediately began developing engineering mitigations and updating our cloud infrastructure," executive wrote in a blog post on Tuesday. (

O> said in a security advisory updated on Tuesday that it has identified 18 vulnerable products, including some of its blade servers, rack servers and routers, and expects to have patches for servers in about five weeks, on February 18. Cisco said it is also looking for problems in nearly 30 other products, including switches and routers. The majority of Cisco's products were not vulnerable because they are "closed systems that do not allow customers to run custom code on the device," it said. The memory corruption flaws, named Meltdown and Spectre, could allow hackers to bypass and other to steal passwords or keys on most types of computers, phones and cloud-based servers.

estimated that around 5 percent of more than its partners have shipped since 1991 was impacted by Spectre. It said the number of chips affected by Meltdown was significantly less.

"ARM will address Spectre in future processors but there will need to be an ongoing discipline in the design of which needs to be addressed through both software and hardware," a said in an emailed statement.

said a typical home and business PC user should not see significant slowdowns in common tasks such as reading email, writing a document or accessing digital photos. (http://ly/2FiL0Hk)

The chipmaker said last week that fixes for security issues in its would not slow down computers, rebuffing concerns that the flaws would significantly reduce performance.

Rival had also played down the threat, saying its products were at "zero risk" from the Meltdown flaw, but that one variant of the Spectre bug could be resolved by from vendors such as

But on Tuesday said it was aware of an issue with some older-generation processors following the installation of a security update that was published over the weekend.

said it was working with to resolve the issues.

also released an updated version of its software on Monday to fix the security flaw.
