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

  - In Network Security Services (NSS) before 3.36.7 and before 3.41.1, a malformed signature can cause a     crash due to a null dereference, resulting in a Denial of Service. (CVE-2018-18508)

  - In Network Security Services before 3.44, a malformed Netscape Certificate Sequence can cause NSS to     crash, resulting in a denial of service. (CVE-2019-17007)

  - A flaw was found in the way NSS handled CCS (ChangeCipherSpec) messages in TLS 1.3. This flaw allows a     remote attacker to send multiple CCS messages, causing a denial of service for servers compiled with the     NSS library. The highest threat from this vulnerability is to system availability. This flaw affects NSS     versions before 3.58. (CVE-2020-25648)

  - 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 remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:0876 advisory.

  - nss: Use-after-free in sftk_FreeSession due to improper refcounting (CVE-2019-11756)

  - nss: Check length of inputs for cryptographic primitives (CVE-2019-17006)

  - nss: Handling of Netscape Certificate Sequences in CERT_DecodeCertPackage() may crash with a NULL deref     leading to DoS (CVE-2019-17007)

  - nss: CHACHA20-POLY1305 decryption with undersized tag leads to out-of-bounds read (CVE-2020-12403)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - In Network Security Services (NSS) before 3.46, several     cryptographic primitives had missing length checks. In     cases where the application calling the library did not     perform a sanity check on the inputs it could result in     a crash due to a buffer overflow.(CVE-2019-17006)

  - NSS has shown timing differences when performing DSA     signatures, which was exploitable and could eventually     leak private keys. This vulnerability affects     Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR <     68.9.(CVE-2020-12399)

  - When converting coordinates from projective to affine,     the modular inversion was not performed in constant     time, resulting in a possible timing-based side channel     attack. This vulnerability affects Firefox < 80 and     Firefox for Android < 80.(CVE-2020-12400)

  - A flaw was found in the way CHACHA20-POLY1305 was     implemented in NSS. When using multi-part Chacha20, it     could cause out-of-bounds reads. This issue was fixed     by explicitly disabling multi-part ChaCha20 (which was     not functioning correctly) and strictly enforcing tag     length. The highest threat from(CVE-2020-12403)
