VCID-3e3b-z5bh-pban
Aliases: CVE-2020-10030 |
An issue has been found in PowerDNS Recursor 4.1.0 up to and including 4.3.0. It allows an attacker (with enough privileges to change the system's hostname) to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not have '\0' termination of the returned string if the hostname is larger than the supplied buffer. (Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname always has '\0' termination.) Under some conditions, this issue can lead to the writing of one '\0' byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution. |

CVE-2020-12244
|
| VCID-2hee-f8gq-rycf | An issue has been found in PowerDNS Recursor versions 4.1.x before 4.1.9 where records in the answer section of responses received from authoritative servers with the AA flag not set were not properly validated, allowing an attacker to bypass DNSSEC validation. |
CVE-2019-3807
|
| VCID-4c2u-n7p5-nfg4 | PowerDNS Authoritative Server 4.1.0 up to 4.1.4 inclusive and PowerDNS Recursor 4.0.0 up to 4.1.4 inclusive are vulnerable to a packet cache pollution via crafted query that can lead to denial of service. |
CVE-2018-14626
|
| VCID-9p7x-52ad-vbh6 | An issue has been found in PowerDNS Recursor from 4.0.0 up to and including 4.1.4. A remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail. |
CVE-2018-14644
|
| VCID-a7xd-fyh3-xuaq | An issue has been found in the DNSSEC parsing code of PowerDNS Recursor from 4.0.0 up to and including 4.0.6 leading to a memory leak when parsing specially crafted DNSSEC ECDSA keys. These keys are only parsed when validation is enabled by setting dnssec to a value other than off or process-no-validate (default). |
CVE-2017-15094
|
| VCID-ch2d-p2ru-23ex | PowerDNS Authoritative Server 3.3.0 up to 4.1.4 excluding 4.1.5 and 4.0.6, and PowerDNS Recursor 3.2 up to 4.1.4 excluding 4.1.5 and 4.0.9, are vulnerable to a memory leak while parsing malformed records that can lead to remote denial of service. |
CVE-2018-10851
|
| VCID-d4km-jg6b-2kh3 | An issue has been found in PowerDNS Recursor before version 4.1.8 where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash. |
CVE-2018-16855
|
| VCID-h73s-nkfg-sqgc | security update |
CVE-2017-15120
|
| VCID-mbq1-b3dr-1uc4 | A cross-site scripting issue has been found in the web interface of PowerDNS Recursor from 4.0.0 up to and including 4.0.6, where the qname of DNS queries was displayed without any escaping, allowing a remote attacker to inject HTML and Javascript code into the web interface, altering the content. |
CVE-2017-15092
|
| VCID-n2k6-nfxs-7ydj | security update |
CVE-2020-10995
|
| VCID-tcp4-6r2n-6uer | When api-config-dir is set to a non-empty value, which is not the case by default, the API in PowerDNS Recursor 4.x up to and including 4.0.6 and 3.x up to and including 3.7.4 allows an authorized user to update the Recursor's ACL by adding and removing netmasks, and to configure forward zones. It was discovered that the new netmask and IP addresses of forwarded zones were not sufficiently validated, allowing an authenticated user to inject new configuration directives into the Recursor's configuration. |
CVE-2017-15093
|
| VCID-urr2-qrfd-vfeh | An issue has been found in the DNSSEC validation component of PowerDNS Recursor from 4.0.0 and up to and including 4.0.6, where the signatures might have been accepted as valid even if the signed data was not in bailiwick of the DNSKEY used to sign it. This allows an attacker in position of man-in-the-middle to alter the content of records by issuing a valid signature for the crafted records. |
CVE-2017-15090
|
| VCID-vua1-5kz6-hban | An issue has been found in PowerDNS Recursor versions after 4.1.3 before 4.1.9 where Lua hooks are not properly applied to queries received over TCP in some specific combination of settings, possibly bypassing security policies enforced using Lua. |
CVE-2019-3806
|
| VCID-xxxv-krt4-tka1 | Improper input validation bugs in DNSSEC validators components in PowerDNS version 4.1.0 allow attacker in man-in-the-middle position to deny existence of some data in DNS via packet replay. |
