The patches resolve two different RCE bugs in Windows Codecs that enable hackers to exploit playback of multimedia data files.
Microsoft has quietly pushed out two crisis protection updates to repair remote code execution bugs in Microsoft Home windows Codecs Library.
Home windows Codecs Library handles how the OS compresses large multimedia documents these types of as pictures and video clips, and then decodes them for playback inside apps. The out-of-band updates, addressing a critical-severity flaw (CVE-2020-1425) and essential-severity vulnerability (CVE-2020-1457), had been sent out by way of Windows Update Tuesday night and impact quite a few variations of Home windows 10 and Windows Server 2019.
Equally vulnerabilities allow for remote code execution “in the way that Microsoft Home windows Codecs Library handles objects in memory,” according to the updates.
CVE-2020-1425, if exploited, could allow an attacker to execute arbitrary code, even though CVE-2020-1457 can be exploited to allow a bad actor to obtain info that would additional compromise the user’s system. The two flaws can be exploited if buyers of affected devices open up corrupted media documents within just applications that use the native Home windows Codecs Library.
Microsoft bundled a comprehensive list of the Windows 10 and Home windows Server distributions influenced in its advisories, which presented very little in conditions of certain depth on the flaws. The organization did say, nonetheless, that there are no mitigations or workarounds for the vulnerabities.

It’s not completely uncommon for Microsoft to release updates outdoors of the 2nd Tuesday of each and every month, also recognised as “Patch Tuesday.” However, usually the enterprise does so in response to vulnerabilities uncovered by third-celebration stability researchers—including from rivals these kinds of as Google — that are identified to be underneath assault. Microsoft said it has not detected either Home windows Codecs Library flaw being exploited in the wild.
These patches come months soon after Microsoft’s frequently scheduled June Patch Tuesday, in which it released patches for 129 vulnerabilities – the maximum number of CVEs ever produced by Microsoft in a solitary thirty day period. Within the blockbuster safety update, 11 vital distant code-execution flaws were being patched in Home windows, SharePoint server, Windows Shell, VBScript and other products and solutions. Not like other new regular updates from Microsoft, its June updates did not consist of any zero-working day vulnerabilities currently being actively attacked in the wild.
