The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2019:1951 advisory.

  - nss: NULL pointer dereference in several CMS functions resulting in a denial of service (CVE-2018-18508)

  - nss: Out-of-bounds read when importing curve25519 private key (CVE-2019-11719)

  - nss: PKCS#1 v1.5 signatures can be used for TLS 1.3 (CVE-2019-11727)

  - nss: Empty or malformed p256-ECDH public keys may trigger a segmentation fault (CVE-2019-11729)

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

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

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has nss packages installed that are affected by multiple vulnerabilities:

  - A vulnerability exists where it possible to force Network Security Services (NSS) to sign     CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in     CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This     vulnerability affects Firefox < 68. (CVE-2019-11727)

  - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger     an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information     disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
    (CVE-2019-11719)

  - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited     to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)

  - 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)

  - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting     in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming     Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)

  - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean     Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform     electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
    *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,     but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. This vulnerability affects     Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)

  - During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar     multiplication was removed, resulting in variable-time execution dependent on secret data. This     vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)

  - 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)

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

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 68.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-28 advisory.

  - When an inner window is reused, it does not consider the     use of document.domain for cross-origin protections. If     pages on different subdomains ever cooperatively use     document.domain, then either page can abuse this to     inject script into arbitrary pages on the other     subdomain, even those that did not use document.domain     to relax their origin security. This vulnerability     affects Firefox ESR < 60.8, Firefox < 68, and     Thunderbird < 60.8. (CVE-2019-11711)

  - POST requests made by NPAPI plugins, such as Flash, that     receive a status 308 redirect response can bypass CORS     requirements. This can allow an attacker to perform     Cross-Site Request Forgery (CSRF) attacks. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11712)

  - A use-after-free vulnerability can occur in HTTP/2 when     a cached HTTP/2 stream is closed while still in use,     resulting in a potentially exploitable crash. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11713)

  - Necko can access a child on the wrong thread during UDP     connections, resulting in a potentially exploitable     crash in some instances. This vulnerability affects     Firefox < 68. (CVE-2019-11714)

  - Empty or malformed p256-ECDH public keys may trigger a     segmentation fault due values being improperly sanitized     before being copied into memory and used. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11729)

  - Due to an error while parsing page content, it is     possible for properly sanitized user input to be     misinterpreted and lead to XSS hazards on web sites in     certain circumstances. This vulnerability affects     Firefox ESR < 60.8, Firefox < 68, and Thunderbird <     60.8. (CVE-2019-11715)

  - Until explicitly accessed by script, window.globalThis     is not enumerable and, as a result, is not visible to     code such as Object.getOwnPropertyNames(window). Sites     that deploy a sandboxing that depends on enumerating and     freezing access to the window object may miss this,     allowing their sandboxes to be bypassed. This     vulnerability affects Firefox < 68. (CVE-2019-11716)

  - A vulnerability exists where the caret (^) character     is improperly escaped constructing some URIs due to it     being used as a separator, allowing for possible     spoofing of origin attributes. This vulnerability     affects Firefox ESR < 60.8, Firefox < 68, and     Thunderbird < 60.8. (CVE-2019-11717)

  - When importing a curve25519 private key in PKCS#8format     with leading 0x00 bytes, it is possible to trigger an     out-of-bounds read in the Network Security Services     (NSS) library. This could lead to information     disclosure. This vulnerability affects Firefox ESR <     60.8, Firefox < 68, and Thunderbird < 60.8.
    (CVE-2019-11719)

  - Some unicode characters are incorrectly treated as     whitespace during the parsing of web content instead of     triggering parsing errors. This allows malicious code to     then be processed, evading cross-site scripting (XSS)     filtering. This vulnerability affects Firefox < 68.
    (CVE-2019-11720)

  - The unicode latin 'kra' character can be used to spoof a     standard 'k' character in the addressbar. This allows     for domain spoofing attacks as do not display as     punycode text, allowing for user confusion. This     vulnerability affects Firefox < 68. (CVE-2019-11721)

  - A vulnerability exists where if a user opens a locally     saved HTML file, this file can use file: URIs to access     other files in the same directory or sub-directories if     the names are known or guessed. The Fetch API can then     be used to read the contents of any files stored in     these directories and they may uploaded to a server. It     was demonstrated that in combination with a popular     Android messaging app, if a malicious HTML attachment is     sent to a user and they opened that attachment in     Firefox, due to that app's predictable pattern for     locally-saved file names, it is possible to read     attachments the victim received from other     correspondents. This vulnerability affects Firefox ESR <     60.8, Firefox < 68, and Thunderbird < 60.8.
    (CVE-2019-11730)

  - A vulnerability exists during the installation of add-     ons where the initial fetch ignored the origin     attributes of the browsing context. This could leak     cookies in private browsing mode or across different     containers for people who use the Firefox Multi-     Account Containers Web Extension. This vulnerability     affects Firefox < 68. (CVE-2019-11723)

  - Application permissions give additional remote     troubleshooting permission to the site     input.mozilla.org, which has been retired and now     redirects to another site. This additional permission is     unnecessary and is a potential vector for malicious     attacks. This vulnerability affects Firefox < 68.
    (CVE-2019-11724)

  - When a user navigates to site marked as unsafe by the     Safebrowsing API, warning messages are displayed and     navigation is interrupted but resources from the same     site loaded through websockets are not blocked, leading     to the loading of unsafe resources and bypassing     safebrowsing protections. This vulnerability affects     Firefox < 68. (CVE-2019-11725)

  - A vulnerability exists where it possible to force     Network Security Services (NSS) to sign     CertificateVerify with PKCS#1 v1.5 signatures when those     are the only ones advertised by server in     CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures     should not be used for TLS 1.3 messages. This     vulnerability affects Firefox < 68. (CVE-2019-11727)

  - The HTTP Alternative Services header, Alt-Svc, can be     used by a malicious site to scan all TCP ports of any     host that the accessible to a user when web content is     loaded. This vulnerability affects Firefox < 68.
    (CVE-2019-11728)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 67. Some of these bugs     showed evidence of memory corruption and we presume that     with enough effort that some of these could be exploited     to run arbitrary code. This vulnerability affects     Firefox < 68. (CVE-2019-11710)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 67 and Firefox ESR 60.7.
    Some of these bugs showed evidence of memory corruption     and we presume that with enough effort that some of     these could be exploited to run arbitrary code. This     vulnerability affects Firefox ESR < 60.8, Firefox < 68,     and Thunderbird < 60.8. (CVE-2019-11709)

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

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 68.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-21 advisory.

  - As part of his winning Pwn2Own entry, Niklas Baumstark     demonstrated a sandbox escape by installing a malicious     language pack and then opening a browser feature that     used the compromised translation. (CVE-2019-9811)

  - When an inner window is reused, it does not consider the     use of document.domain for cross-origin     protections. If pages on different subdomains ever     cooperatively use document.domain, then     either page can abuse this to inject script into     arbitrary pages on the other subdomain, even those that     did not use document.domain to relax their     origin security.

  - Activity Stream can display content from sent from the     Snippet Service website. This content is written to     innerHTML on the Activity Stream page     without sanitization, allowing for a potential access to     other information available to the Activity Stream, such     as browsing history, if the Snipper Service were     compromised. (CVE-2019-11718)

  - When importing a curve25519 private key in PKCS#8format     with leading 0x00 bytes, it is possible to trigger an     out-of-bounds read in the Network Security Services     (NSS) library. This could lead to information     disclosure. (CVE-2019-11719)

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14418-1 advisory.

  - A vulnerability exists where it possible to force Network Security Services (NSS) to sign     CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in     CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This     vulnerability affects Firefox < 68. (CVE-2019-11727)

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

  - 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)

  - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean     Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform     electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
    *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,     but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

  - 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)

  - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting     in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming     Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)

  - 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)

  - During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar     multiplication was removed, resulting in variable-time execution dependent on secret data. This     vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)

  - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean     Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform     electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.
    *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,     but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)

  - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. 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 this vulnerability is to confidentiality and system availability. (CVE-2020-12403)

  - When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which     leaked partial information about the nonce used during signature generation. Given an electro-magnetic     trace of a few signature generations, the private key could have been computed. This vulnerability affects     Firefox < 80 and Firefox for Android < 80. (CVE-2020-6829)

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