Mimecast Research Labs has uncovered a significant bug in Microsoft Office products, which has since been patched by Microsoft.<\/p>\n
In a blog post<\/strong><\/a>, Mimecast explains that the vulnerability is likely to have caused the “widespread, unintended leakage of sensitive information in millions of previously created Office files”.<\/p>\n Mimecast said it found the vulnerability while investigating what it initially thought to be a “false positive” malware detection report from one of its customers.<\/p>\n Instead, it turned out Microsoft Office had a memory leak that had the potential to allow for the unintentional disclosure of users’ data from any Office suite that was utilising ActiveX.<\/p>\n Mimecast said that the vulnerability was classified as “important” by Microsoft, and was patched.<\/p>\n According to Microsoft’s classification levels, this means it could have caused the\u00a0\u201ccompromise of the confidentiality, integrity, or availability of a user\u2019s data, or of the integrity or availability of processing resources\u201d, said Mimecast.<\/p>\n Mimecast reported the vulnerability to Microsoft in November, and it was patched in yesterday’s 8 January CVE-2019-0560 patch.<\/p>\n However, Mimecast recommends removing or re-saving files created by vulnerable versions of Office as these files may still be compromised.<\/p>\n Mimecast said it found a vulnerability in Microsoft Office while investigating what it thought at the time to be a “false positive” malware detection.<\/p>\n","protected":false},"author":341039,"featured_media":212636,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[15227,6599,12213,40988],"class_list":["post-291480","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-security","tag-cybersecurity","tag-microsoft-office","tag-mimecast","tag-security-vulnerability"],"_links":{"self":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/291480"}],"collection":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/users\/341039"}],"replies":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/comments?post=291480"}],"version-history":[{"count":1,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/291480\/revisions"}],"predecessor-version":[{"id":291484,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/291480\/revisions\/291484"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media\/212636"}],"wp:attachment":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media?parent=291480"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/categories?post=291480"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/tags?post=291480"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Microsoft’s response<\/h3>\n
