This article presents the current status of vulnerabilities affecting Windows versions that we have "security adopted" , as well as the current status of our micropatches issued for these vulnerabilities. Note that in order for us to issue a micropatch for a vulnerability, we must consider it high-risk and have a test case ("POC", proof-of-concept) at hand to be able to reproduce and analyze the issue. Accordingly, only vulnerabilities currently eligible for micropatching are included in the table.
The table below will be continually updated with status changes (e.g., if a vulnerability becomes exploited, if our risk assessment changes, when we issue a micropatch) and new eligible vulnerabilities as we become aware of them either through Microsoft's documentation or other sources (e.g., a vulnerability getting published or privately reported to us).
For any questions please contact support@0patch.com.

Micropatch issued on 2/19/2020 for Windows 7 / Server 2008 R2, and previous "temporary workaround" micropatch (402) revoked for these platforms Micropatch issued on 2/21/2020 for Windows 10 v1903/v1909 and previous "temporary workaround" micropatch (407) revoked for these platforms Note: this micropatch modifies the behavior of JScript function sort such that calling it with a callback function will behave as if it was called without one (i.e., sort will always perform a string-based sort). We assess this will affect a small number of applications, and not in a critical way. ("Temporary workaround" micropatches 403, 404, 405, 407 remain in place for other platforms.) |
