Medium: bind

Issue Overview: It was found that the lightweight resolver could crash due to an error when asked to resolve a query name which, when combined with a search list entry, exceeds the maximum allowable length. A remote attacker could use this flaw to crash lwresd or named when using the "lwres"...

ISC BIND lwresd Query Name Denial of Service (CVE-2016-2775)

A denial-of-service vulnerability exists in ISC BIND. The vulnerability is due to failure to check the query length when using lightweight resolver protocol. A remote, unauthenticated attacker could exploit this vulnerability by sending crafted queries potentially leading to denial-of-service...

Cisco Nexus 3000 / 9000 Series GNU C Library (glibc) getaddrinfo() RCE (cisco-sa-20160218-glibc)

The version of Cisco NX-OS software running on the remote device is affected by a remote code execution vulnerability in the bundled version of the GNU C Library glibc due to a stack-based buffer overflow condition in the DNS resolver. An unauthenticated, remote attacker can exploit this, via a...

[SECURITY] Fedora 23 Update: bind-9.10.4-1.P2.fc23

BIND Berkeley Internet Name Domain is an implementation of the DNS Domain Name System protocols. BIND includes a DNS server named, which resolves host names to IP addresses; a resolver library routines for applications to use when interfacing with DNS; and tools for verifying that the DNS server ...

Glibc DNS Resolver Vulnerability

A vulnerability in the GNU libc glibc DNS resolver allows remote code execution CVE-2015-7547. However, this issue can be exploited only from a DNS server that is under the control of an attacker. Ref 91886. This glibc issue is only exploitable by an attacker controlling the DNS server configured...

CVE-2016-5417

Memory leak in the resvinit function in the IPv6 name server management code in libresolv in GNU C Library aka glibc or libc6 before 2.24 allows remote attackers to cause a denial of service memory consumption by leveraging partial initialization of internal resolver data structures...

ISC BIND 9.x < 9.9.9-P2 / 9.10.x < 9.10.4-P2 / 9.11.0a3 < 9.11.0b2 lwres Query DoS

According to its self-reported version number, the installation of ISC BIND running on the remote name server is 9.x prior to 9.9.9-P2, 9.10.x prior to 9.10.4-P2, or 9.11.0a3 prior to 9.11.0b2. It is, therefore, affected by an error in the lightweight resolver lwres protocol implementation when...

bind: denial of service

Although not commonly used, the BIND package contains provisions to allow systems to resolve names using the lightweight resolver protocol, a protocol similar to but distinct from the normal DNS protocols. The lightweight resolver protocol can be used either by running the lwresd utility installe...
