According to the version of the nss packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was found that certain cryptographic primitives in nss, the Network Security Service libraries, did not check the length of the input text. This could result in a potential heap-based buffer overflow.

For Debian 8 'Jessie', this problem has been fixed in version 2:3.26-1+debu8u10.

We recommend that you upgrade your nss packages.

This update for mozilla-nspr, mozilla-nss fixes the following issues :

mozilla-nss was updated to NSS 3.47.1 :

Security issues fixed :

CVE-2019-17006: Added length checks for cryptographic primitives (bsc#1159819).

CVE-2019-11745: EncryptUpdate should use maxout, not block size (bsc#1158527).

CVE-2019-11727: Fixed vulnerability sign CertificateVerify with PKCS#1 v1.5 signatures issue (bsc#1141322).

mozilla-nspr was updated to version 4.23: Whitespace in C files was cleaned up and no longer uses tab characters for indenting.

According to the versions of the nss-softokn packages installed, the EulerOS 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)

  - 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.(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.(CVE-2020-12402)

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2020:3280 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: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state (CVE-2019-17023)

According to the versions of the nss-softokn packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - 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 this vulnerability is     to confidentiality and system     availability.(CVE-2020-12403)

  - 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)

  - 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)

  - 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.

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)

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)

  - 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)
