An issue was discovered in MaraDNS Deadwood through 3.5.0021 that allows variant V1 of unintended domain name resolution. A revoked domain name can still be resolvable for a long time, including expired domains and taken-down malicious domains. The effects of an exploit would be widespread and highly impactful, because the exploitation conforms to de facto DNS specifications and operational practices, and overcomes current mitigation patches for "Ghost" domain names.

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-3dd938a14d advisory.

    Automatic update for maradns-3.5.0036-1.fc39.

  - An issue was discovered in MaraDNS Deadwood through 3.5.0021 that allows variant V1 of unintended domain     name resolution. A revoked domain name can still be resolvable for a long time, including expired domains     and taken-down malicious domains. The effects of an exploit would be widespread and highly impactful,     because the exploitation conforms to de facto DNS specifications and operational practices, and overcomes     current mitigation patches for Ghost domain names. (CVE-2022-30256)

  - MaraDNS is open-source software that implements the Domain Name System (DNS). In version 3.5.0024 and     prior, a remotely exploitable integer underflow vulnerability in the DNS packet decompression function     allows an attacker to cause a Denial of Service by triggering an abnormal program termination. The     vulnerability exists in the `decomp_get_rddata` function within the `Decompress.c` file. When handling a     DNS packet with an Answer RR of qtype 16 (TXT record) and any qclass, if the `rdlength` is smaller than     `rdata`, the result of the line `Decompress.c:886` is a negative number `len = rdlength - total;`. This     value is then passed to the `decomp_append_bytes` function without proper validation, causing the program     to attempt to allocate a massive chunk of memory that is impossible to allocate. Consequently, the program     exits with an error code of 64, causing a Denial of Service. One proposed fix for this vulnerability is to     patch `Decompress.c:887` by breaking `if(len <= 0)`, which has been incorporated in version 3.5.0036 via     commit bab062bde40b2ae8a91eecd522e84d8b993bab58. (CVE-2023-31137)
