About this tag
The cve 2026 57432 tag covers a Perl security flaw in versions through 5.43.10, where a malicious pack or unpack template can cause an integer overflow and read beyond a heap buffer. Coverage focuses on remediation for Windows administrators and developers, including inventorying standalone Perl installations, Git for Windows, MSYS2, Cygwin, CI runners, and other toolchains. The issue is an upstream Perl vulnerability rather than a flaw in the Windows operating system, so Windows Update should not be the assumed fix. The tagged guidance also covers the July 13, 2026 disclosure, Perl 5.43.11 as the first development release with a fix, and Microsoft’s later MSRC listing.
