2) Input validation error

EUVDB-ID: #VU32395

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-5722

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

buffer.c in named in ISC BIND 9.x before 9.9.7-P3 and 9.10.x before 9.10.2-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) by creating a zone containing a malformed DNSSEC key and issuing a query for a name in that zone.

3) Assertion failure

EUVDB-ID: #VU3848

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2015-8000

CWE-ID: CWE-617 - Reachable Assertion

Exploit availability: No

Description

A remote attacker can trigger denial of service (DoS) conditions.

The vulnerability exists due to a parsing error when processing incoming responses within db.c file. A remote attacker who can cause a server to request a record with a malformed class attribute can use this bug to trigger a REQUIRE assertion, causing named to exit and denying service to clients.

Successful exploitation of this vulnerability may allow an attacker to perform a denial of service (DoS) attack.

Mitigation

Update the affected packages.
