Security News > 2020 > February > IE zero day and heap of RDP flaws fixed in February Patch Tuesday
The fix is part of the February Patch Tuesday update that features a record 99 security vulnerabilities including 12 marked as 'critical' and 87 'important'.
The first indication of the IE zero-day, now identified as CVE-2020-0674, appeared when Mozilla fixed a very similar issue in Firefox on 8 January, less than two days after the appearance of version 72.
The attacks were reported to Mozilla by a third party which, in a later deleted reference, mentioned that the same issue also affected IE. On 17 January, Microsoft issued its own alert regarding the Scripting Engine memory corruption flaw, citing IE's Enhanced Security Configuration protection as mitigation against attacks.
Another critical is CVE-2020-0738 - a memory corruption flaw in Windows Media Foundation, while CVE-2020-0689, marked important, could offer attackers a way around Microsoft Secure Boot.
Adobe's February update features 42 CVEs, including 21 criticals in Framemaker alone.
