The version of AHV installed on the remote host is prior to 20201105.2286. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20201105.2286 advisory.

  - A flaw was found in OpenLDAP. This flaw allows an attacker who can send a malicious packet to be processed     by OpenLDAP's slapd server, to trigger an assertion failure. The highest threat from this vulnerability is     to system availability. (CVE-2020-25709)

  - A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious     packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this     vulnerability is to system availability. (CVE-2020-25710)

  - An issue was discovered in SaltStack Salt before 3003.3. A user who has control of the source, and     source_hash URLs can gain full file system access as root on a salt minion. (CVE-2021-21996)

  - 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)

  - In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for     m_groupSize. (CVE-2021-46143)

  - The BN_mod_sqrt() function, which computes a modular square root, contains a bug that can cause it to loop     forever for non-prime moduli. Internally this function is used when parsing certificates that contain     elliptic curve public keys in compressed form or explicit elliptic curve parameters with a base point     encoded in compressed form. It is possible to trigger the infinite loop by crafting a certificate that has     invalid explicit curve parameters. Since certificate parsing happens prior to verification of the     certificate signature, any process that parses an externally supplied certificate may thus be subject to a     denial of service attack. The infinite loop can also be reached when parsing crafted private keys as they     can contain explicit elliptic curve parameters. Thus vulnerable situations include: - TLS clients     consuming server certificates - TLS servers consuming client certificates - Hosting providers taking     certificates or private keys from customers - Certificate authorities parsing certification requests from     subscribers - Anything else which parses ASN.1 elliptic curve parameters Also any other applications that     use the BN_mod_sqrt() where the attacker can control the parameter values are vulnerable to this DoS     issue. In the OpenSSL 1.0.2 version the public key is not parsed during initial parsing of the certificate     which makes it slightly harder to trigger the infinite loop. However any operation which requires the     public key from the certificate will trigger the infinite loop. In particular the attacker can use a self-     signed certificate to trigger the loop during verification of the certificate signature. This issue     affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was addressed in the releases of 1.1.1n and 3.0.2 on the     15th March 2022. Fixed in OpenSSL 3.0.2 (Affected 3.0.0,3.0.1). Fixed in OpenSSL 1.1.1n (Affected     1.1.1-1.1.1m). Fixed in OpenSSL 1.0.2zd (Affected 1.0.2-1.0.2zc). (CVE-2022-0778)

  - xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks     for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

  - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters     into namespace URIs. (CVE-2022-25236)
