The version of nss installed on the remote host is prior to 3.83.0-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-223 advisory.

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.

The version of AOS installed on the remote host is prior to 5.20.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.3 advisory.

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
    (CVE-2021-33037)

  - A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked     down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to further increase their privileges to that of a     running kernel. (CVE-2020-27777)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)
