VCID-1xgw-uan4-byhg
Aliases: CVE-2021-43527 |
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. |

VCID-54s7-rrtw-a7cg
Aliases: CVE-2020-12402 |
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. We would like to thank Sohaib ul Hassan for contributing a fix for this issue as well.*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. |

VCID-ake6-cm2x-8ubs
Aliases: CVE-2019-11745 |
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. |

VCID-axss-jrt6-qqdk
Aliases: CVE-2020-25648 |
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. |

VCID-bjhc-gzeg-vyhq
Aliases: CVE-2019-11719 |
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. |

VCID-c5su-4v3n-5qh4
Aliases: CVE-2020-12401 |

VCID-ex9u-mprs-bqfe
Aliases: CVE-2018-18508 |

VCID-hvj7-bwkf-f3em
Aliases: CVE-2020-6829 |
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. |

VCID-nzee-g5hm-pfca
Aliases: CVE-2018-12384 |
When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not impact TLS 1.3. |

VCID-pjmh-gvqz-47et
Aliases: CVE-2023-4421 |
The NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key. The issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper. |

VCID-sv69-65sj-vybj
Aliases: CVE-2020-12400 |

VCID-tkkj-f8ww-1kdn
Aliases: CVE-2020-12403 |
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. |

VCID-w27h-8fnv-guhx
Aliases: CVE-2019-11727 |
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. |

VCID-wqhe-hmdh-p7eq
Aliases: CVE-2017-7805 |
During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash. |
Affected by 21 other vulnerabilities. |

VCID-z5tc-zwsb-eydp
Aliases: CVE-2018-12404 |
