(Red Hat Issues Fix) BIND Recursion Processing Error in 'netaddr.c' Lets Remote Users Cause the Target 'named' Service to Crash
SecurityTracker Alert ID:  1040482
SecurityTracker URL:  http://securitytracker.com/id/1040482
CVE Reference:   CVE-2017-3145   (Links to External Site)
Date:  Mar 12 2018
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, 9.12.0a1 to 9.12.0rc1
Description:   A vulnerability was reported in BIND. A remote user can cause the target service to crash.

The system does not properly sequence cleanup operations for upstream recursion fetch contexts. A remote server can return specially crafted data to trigger a use-after-free memory error and cause the target named service to crash.

[Editor's note: The vendor indicates that there are no known exploit paths in the code prior to the fix for CVE-2017-3137.]

Jayachandran Palanisamy of Cygate AB reported this vulnerability.

Impact:   A remote user can cause the target service to crash.
Solution:   Red Hat has issued a fix for CVE-2017-3145.
