Telecoms group Vodafone found security flaws in equipment supplied by China's Huawei to its Italian business in 2011 and 2012, the two companies said on Tuesday.
Vodafone, Europe's biggest telecoms group, said it had found security vulnerabilities in two products and that both incidents had been resolved quickly.
Huawei said it was made aware of historical vulnerabilities in 2011 and 2012 and that they had been addressed at the time, according to Reuters.
"Software vulnerabilities are an industry-wide challenge," the Chinese firm said. "Like every Information and Communications Technology vendor we have a well-established public notification and patching process, and when a vulnerability is identified we work closely with our partners to take the appropriate corrective action."
The news comes after the British envoy to the United Nations said the UK was open to working with Chinese companies including Huawei as long as the country’s national security isn’t jeopardised, putting the ally at odds with the Trump administration on a top foreign policy issue.
“We will not take a decision that would compromise British national security,” UN Ambassador Karen Pierce told Bloomberg on Monday. “There are some issues where we don’t wholly share the analysis of the US, much as we share the same strategic policy.”
The US has sought to persuade its allies to ban all Huawei products from next-generation 5G telecommunications networks, contending that components made by the Chinese company could be used for spying purposes, but the American efforts have had limited success. Ramping up the threats, secretary of state Michael Pompeo this month said the US might hold back intelligence-sharing with Nato allies if the Chinese technology is part of their communications systems.
“We’ve made clear that if the risk exceeds the threshold for the United States, we simply won’t be able to share that information any longer,” Mr Pompeo said on April 4 after meeting with counterparts from Nato in Washington.
