Denial of service in ISC BIND - CVE-2013-4854

Vulnerability identifier: #VU4572

CSH Severity: High

CVSS v4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2013-4854

CWE-ID: CWE-388

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause DoS conditions on the target system.

The weakness exists due to an error in the RFC 5011 implementation in rdata.c when parsing RDATA within a DNS query. By using a query with a malformed RDATA section that is not properly handled during construction of a log message, a remote attacker can cause an assertion failure and named daemon exit.

Successful exploitation of the vulnerability results in denial of service on the vulnerable system.

Note: the vulnerability was being actively exploited.
