    Integer overflow in base64

    CVE-2017-1000430 · GHSA-x67x-vg9m-65c3

    Affected
    • crates.io base64 < 0.5.2
    Fixed in
    0.5.2· Vendor fix available
    Issue
    Affected versions of this crate suffered from an integer overflow bug when calculating the size of a buffer to use when encoding base64 using the encodeconfigbuf and encodeconfig functions. If the input string was large, this would cause a buffer to be allocated that was too small. Since this function writes to the buffer using unsafe code, it would allow an attacker to write beyond the buffer, causing memory corruption and possibly the execution of arbitrary code. This flaw was corrected by using checked arithmetic to calculate the size of the buffer.

    Recommended action: Upgrade to 0.5.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
