The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5441 advisory.

  - 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.

    Xiang Li discovered that MaraDNS incorrectly handled certain inputs. If a user or an automated system were     tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to     obtain sensitive information. (CVE-2022-30256)
