Vulnerability from variot
A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1, 9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND 9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1. ISC BIND 9 There is a service disruption (DoS) Vulnerabilities exist. An attacker can exploit this issue to cause a denial-of-service condition. ISC BIND is a set of open source software developed by ISC Corporation in the United States that implements the DNS protocol. The vulnerability stems from the improper handling of concurrent access when concurrent codes need to access shared resources mutually exclusive during the running of the network system or product. An attacker could exploit this vulnerability by sending a request that submits malicious input to the targeted system.
ISC has confirmed the vulnerability and released software updates. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
