Microsoft Patches Windows XP Again As Part of June Patch Tuesday

Last month, in reaction to the WannaCry outbreak that affected Windows users all over the world, Microsoft released a patch for Windows XP—an operating system it had stopped supporting in 2014. As part of the June Patch Tuesday cycle, Microsoft has decided to issue patches for XP and other older platforms that have reached End of Support (EOS) status. They cited the “elevated risk of cyber attacks by government organizations, sometimes referred to as nation-states” that could use the now-fixed vulnerabilities. These fixes are on top of the patches for supported versions of Windows that are also part of this month’s cycle.

This batch of updates is particularly large—96 CVEs for Windows, Internet Explorer, Microsoft Office, Skype, and the Edge browser. Out of this group, there are a couple of items that require particular attention:

    • CVE-2017-8543: present in most Windows versions, it is a feature that handles file and printer sharing (Server Message Block or SMB). Potentially, if left unpatched on a network this vulnerability could be exploited to affect all vulnerable connected systems very rapidly.
    • CVE-2017-8464: a LNK Remote Code Execution (RCE) vulnerability that allows RCE if a specifically crafted shortcut is displayed.

Aside from the above, Microsoft has also identified several vulnerabilities that they presume to be under imminent attack and should be considered priority updates:

    • CVE-2017-0176: This vulnerability exists if the Remote Desktop Protocol (RDP) server has Smart Card authentication enabled.  It could allow an attacker to execute malicious code on the target system.
    • CVE-2017-0222: If Internet Explorer improperly accesses objects in memory, the memory could be corrupted in such a way that an attacker could execute arbitrary code in the context of the current user, and also gain the same user rights.
    • CVE-2017-0267 and CVE-2017-0280: The most critical of these vulnerabilities could also allow RCE if an attacker sends specially crafted packets to a Microsoft Server Message Block 1.0 (SMBv1) server.
    • CVE-2017-7269: The vulnerability exists if WebDAV improperly handles objects in memory, which could allow an attacker to run arbitrary code on the user’s system.
    • CVE-2017-8461: A remote code execution vulnerability exists in RPC if the server has Routing and Remote Access enabled. An attacker who successfully exploits this vulnerability could execute code on the target system.
    • CVE-2017-8487: A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code.
    • CVE-2017-8552: An elevation of privilege vulnerability exists when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode.

Adobe has also issued patches for Flash Player, Shockwave Player, Captivate and Adobe Digital Editions. All of the critical vulnerabilities in the Adobe Flash Player could lead to remote code execution (APSB17-17), while the critical vulnerabilities categorized as “Memory Corruption” in the Adobe Digital Editions (APSB17-20) can also lead to remote code execution. Users are encouraged to update to the latest version of Adobe Flash Player, which is 26.0.0.126. For Edge and IE 11 users it is version 26.0.0.120.
