Apache HTTP Server 2.4.49: a path-traversal fix that needed a second fix
CVE-2021-41773 was a path traversal in Apache httpd 2.4.49 that could leak files and, with CGI enabled, reach RCE. The 2.4.50 fix was incomplete, so CVE-2021-42013 followed days later. Two CVEs, one bug, a textbook patch-the-patch.

The same crew beat the same defense twice in three months. The patch was the problem.
CVE-2023-24880 let Magniber ransomware bypass SmartScreen with malformed MSI signatures. It worked because Microsoft's earlier fix for nearly the same bug addressed one symptom and left the root cause standing. Narrow patches invite variants, and the attacker just comes back.
