      SoX ".WAV" ICRD and ISFT Buffer Overflow
    ------------------------------------------------------------------------

    SUMMARY

    SoX is a "universal sound sample translator". Two buffer overflows have
    been found in SoX, allowing a remote attacker that can fool a user into
    listening into a maliciously created WAV with the SoX product to execute
    arbitrary code under the user privileges.

    DETAILS

    Vulnerable Systems:
     * SoX version 12.17.4 and prior

    The two vulnerabilities can be found inside the wav.c file and are caused
    by inadequate testing done on the length received from the WAV header
    file. Both vulnerabilities are located inside the st_wavstartread().

    ADDITIONAL INFORMATION

    The information has been provided by Ulf Harnhammar.
