Summary

The DNS map code in Sendmail 8.12.8 and earlier, when using the "enhdnsbl" feature, does not properly initialize certain data structures, which allows remote attackers to cause a denial of service (process crash) via an invalid DNS response that causes Sendmail to free incorrect data.

    NASL idMANDRAKE_MDKSA-2003-086.NASL
    descriptionA vulnerability was discovered in all 8.12.x versions of sendmail up to and including 8.12.8. Due to wrong initialization of RESOURCE_RECORD_T structures, if sendmail receives a bad DNS reply it will call free() on random addresses which usually causes sendmail to crash. These updated packages are patched to fix the problem.
