The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3767-1 advisory.

    Update to release 9.16.33:

    - CVE-2022-2795: Fixed potential performance degredation due to missing database lookup limits when     processing large delegations (bsc#1203614).
    - CVE-2022-3080: Fixed assertion failure when there was a stale CNAME in the cache for the incoming query     and the stale-answer-client-timeout option is set to 0 (bsc#1203618).
    - CVE-2022-38177: Fixed a memory leak that could be externally triggered in the DNSSEC verification code     for the ECDSA algorithm (bsc#1203619).
    - CVE-2022-38178: Fixed memory leaks that could be externally triggered in the DNSSEC verification code     for the EdDSA algorithm (bsc#1203620).

    - Add systemd drop-in directory for named service (bsc#1201689).
    - Add modified createNamedConfInclude script and README-bind.chrootenv (bsc#1203250).

    - Feature Changes:
      - Response Rate Limiting (RRL) code now treats all QNAMEs that are       subject to wildcard processing within a given zone as the same       name, to prevent circumventing the limits enforced by RRL.

      - Zones using dnssec-policy now require dynamic DNS or       inline-signing to be configured explicitly.

      - A backward-compatible approach was implemented for encoding       internationalized domain names (IDN) in dig and converting the       domain to IDNA2008 form; if that fails,       BIND tries an IDNA2003 conversion.

      - The DNSSEC algorithms RSASHA1 and NSEC3RSASHA1 are now automatically       disabled on systems where they are disallowed by the security policy.
      Primary zones using those algorithms need to be migrated to new algorithms       prior to running on these systems, as graceful migration to different DNSSEC       algorithms is not possible when RSASHA1 is disallowed by the operating system.

      - Log messages related to fetch limiting have been improved to provide       more complete information. Specifically, the final counts of allowed       and spilled fetches are now logged before the counter object is destroyed.

      - Non-dynamic zones that inherit dnssec-policy from the view or options       blocks were not marked as inline-signed and therefore never scheduled       to be re-signed. This has been fixed.

      - The old max-zone-ttl zone option was meant to be superseded by       the max-zone-ttl option in dnssec-policy; however, the latter option       was not fully effective. This has been corrected: zones no longer load       if they contain TTLs greater than the limit configured in dnssec-policy.
      For zones with both the old max-zone-ttl option and dnssec-policy       configured, the old option is ignored, and a warning is generated.

      - rndc dumpdb -expired was fixed to include expired RRsets,       even if stale-cache-enable is set to no and the cache-cleaning time       window has passed. (jsc#SLE-24600)

According to the versions of the bind packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - By flooding the target resolver with queries exploiting this flaw an attacker can significantly impair the     resolver's performance, effectively denying legitimate clients access to the DNS resolution service.
    (CVE-2022-2795)

  - By sending specific queries to the resolver, an attacker can cause named to crash. (CVE-2022-3080)

  - By spoofing the target resolver with responses that have a malformed ECDSA signature, an attacker can     trigger a small memory leak. It is possible to gradually erode available memory to the point where named     crashes for lack of resources. (CVE-2022-38177)

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.207 advisory.

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

  - urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as     demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this     is similar to CVE-2020-26116. (CVE-2020-26137)

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0071 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2022-3094:
      A flaw was found in Bind, where sending a flood of dynamic DNS updates may cause named to allocate large     amounts of memory. This issue may cause named to exit due to a lack of free memory, resulting in a denial     of service (DoS).
      CVE-2022-3094:
      A flaw was found in Bind, where sending a flood of dynamic DNS updates may cause named to allocate large     amounts of memory. This issue may cause named to exit due to a lack of free memory, resulting in a denial     of service (DoS).
      CVE-2022-3736:
      A flaw was found in Bind, where a resolver crash is possible. When stale cache and stale answers are     enabled, the option stale-answer-client-timeout is set to a positive integer, and the resolver receives an     RRSIG query.
      CVE-2022-3924:
      A flaw was found in Bind. When resolver receives many queries requiring recursion, there will be a     corresponding increase in the number of clients waiting for recursion to complete. This may, under certain     conditions, lead to an assertion failure and a denial of service.
      CVE-2022-2795:
      A flaw was found in bind. When flooding the target resolver with special queries, an attacker can     significantly impair the resolver's performance, effectively denying legitimate clients access to the DNS     resolution service.
      CVE-2022-3080:
      A flaw was found in the Bind package, where the resolver can crash when stale cache and stale answers     are enabled, option stale-answer-client-timeout is set to 0 and there is a stale CNAME in the cache for an     incoming query. By sending specific queries to the resolver, an attacker can cause named to crash.
      CVE-2022-38177:
      A flaw was found in the Bind package. By spoofing the target resolver with responses that have a     malformed ECDSA signature, an attacker can trigger a small memory leak, resulting in crashing the program.
      CVE-2022-38178:
      A flaw was found in the Bind package, where the DNSSEC verification code for the EdDSA algorithm leaks     memory when there is a signature length mismatch. By spoofing the target resolver with responses that have     a malformed EdDSA signature, an attacker can trigger a small memory leak, resulting in crashing the     program.
      CVE-2021-25220:
      A cache poisoning vulnerability was found in BIND when using forwarders. Bogus NS records supplied by     the forwarders may be cached and used by name if it needs to recurse for any reason. This issue causes it     to obtain and pass on potentially incorrect answers. This flaw allows a remote high privileged attacker to     manipulate cache results with incorrect records, leading to queries made to the wrong servers, possibly     resulting in false information received on the client's end.
