Description

  • CVE-2007-2925 - allow-query-cache/allow-recursion default acls not set

    • workaround - disable recursion or explicitly set allow-query-cache and allow-recursion acls
  • CVE-2007-2926 - cryptographically weak query id generator

    • 1 in 8 chance of guessing the next query id for 50% of the query ids

    • allows cache-poisoning type of attack, no workaround, affect only outgoing queries

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
