    Use of Uninitialized Resource in tectonic_xdv

    CVE-2021-45703 · GHSA-qwvx-c8j7-5g75

    Affected
    • crates.io tectonic_xdv < 0.1.12
    Fixed in
    0.1.12· Vendor fix available
    Issue
    Affected versions of this crate passes an uninitialized buffer to a user-provided Read implementation. Arbitrary Read implementations can read from the uninitialized buffer (memory exposure) and also can return incorrect number of bytes written to the buffer. Reading from uninitialized memory produces undefined values that can quickly invoke undefined behavior. The problem was fixed in commit cdff034 by zero-initializing the buffer before passing it to a user-provided Read implementation.

    Recommended action: Upgrade to 0.1.12 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
