    Uninitialized memory exposure in claxon

    CVE-2018-20992 · GHSA-8c6g-4xc5-w96c

    Affected
    • crates.io claxon >= 0.4.0, < 0.4.1; < 0.3.2
    Fixed in
    0.3.20.4.1· Vendor fix available
    Issue
    Affected versions of Claxon made an invalid assumption about the decode buffer size being a multiple of a value read from the bitstream. This could cause parts of the decode buffer to not be overwritten. If the decode buffer was newly allocated and uninitialized, this uninitialized memory could be exposed. This allows an attacker to observe parts of the uninitialized memory in the decoded audio stream. The flaw was corrected by checking that the value read from the bitstream divides the decode buffer size, and returning a format error if it does not. If an error is returned, the decode buffer is not exposed. Regression tests and an additional fuzzer have been added to prevent similar flaws in the future.

    Recommended action: Upgrade to 0.4.1 or 0.3.2 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
