    <Details xml:lang="en:us" source="Mitre">
fzf is vulnerable to Integer Overflow leading to crash in FuzzyMatchV2 function. When input line length is approximately 2,200,000 bytes and pattern length is 999 bytes, the product overflows. The Go runtime detects the invalid slice bounds and terminates the process immediately with a non-recoverable panic.

This issue was fixed in version 0.73.1.
    </Details>
    <Details xml:lang="en:us" source="Red Hat">
A flaw was found in fzf. An integer overflow vulnerability exists in the FuzzyMatchV2 function when processing exceptionally long input lines and patterns. This can lead to the application terminating unexpectedly with a non-recoverable panic, resulting in a Denial of Service (DoS). A local user could exploit this by providing specially crafted input.
    </Details>
    <Statement xml:lang="en:us">
A flaw was found in fzf, a command-line fuzzy finder. An integer overflow in the FuzzyMatchV2 function can cause a non-recoverable Go runtime panic when processing a specially crafted input of approximately 2.2 million bytes with a 999-byte pattern. Exploitation requires local access and user interaction — an attacker must supply the crafted input to a running fzf process.
    </Statement>
    <Mitigation xml:lang="en:us">
No mitigation is available for this vulnerability. The panic is non-recoverable once triggered. Users should upgrade to fzf 0.73.1 or later.
    </Mitigation>
