    Denial of Service (DoS)

    fflate is a High performance (de)compression in an 8kB package

    Affected versions of this package are vulnerable to Denial of Service (DoS) via the unzipSync function when parsing malformed ZIP64 archives. An attacker can cause the process to enter an infinite loop by providing a crafted ZIP archive with a central directory entry declaring a compressed size of 0xFFFFFFFF but missing the required ZIP64 extra field tag, resulting in out-of-bounds reads and persistent loop conditions.

    How to fix Denial of Service (DoS)?

    Upgrade fflate to version 0.4.9, 0.5.4, 0.6.11, 0.7.5, 0.8.3 or higher.

    >=0.4.5 <0.4.9>=0.5.0 <0.5.4>=0.6.0 <0.6.11>=0.7.0 <0.7.5>=0.8.0 <0.8.3
