CVE-2008-3432
Heap-based buffer overflow in the mch_expand_wildcards function in os_unix.c in Vim 6.2 and 6.3 allows user-assisted attackers to execute arbitrary code via shell metacharacters in filenames, as demonstrated by the netrw.v3 test case.
Does this matter?
A public exploit is published in Exploit-DB (verified), so the technical barrier is gone even though the severity is medium and EPSS is 8.6%. Treat it as high on anything reachable from the internet.
