CVE-2018-18508

CVE-2018-18508 affects Network Security Services (NSS) prior to 3.36.7 and prior to 3.41.1, where a malformed signature can trigger a null-dereference crash and cause a Denial of Service. The issue is caused by mishandling of signatures in NSS that leads to a crash under certain conditions when v...

nss: Out-of-bounds read when importing curve25519 private key

When importing a curve25519 private key in PKCS8format 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...

nss: ECDSA timing attack mitigation bypass

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDS...

nss: Use-after-free in sftk_FreeSession due to improper refcounting

A use-after-free flaw was found in Mozilla Network Security Services NSS related to PK11 session handling. An attacker could use this flaw to execute arbitrary code with the permissions of the user running the application compiled with NSS...

nss: Side channel vulnerabilities during RSA key generation

A flaw was found in NSS, where it is vulnerable to RSA key generation cache timing side-channel attacks. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. The highest threat to this flaw is to confidentiality...

nss: TLS 1.3 HelloRetryRequest downgrade request sets client into invalid state

A protocol downgrade flaw was found in Network Security Services NSS. After a HelloRetryRequest has been sent, the client may negotiate a lower protocol than TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data...

nss: PKCS#1 v1.5 signatures can be used for TLS 1.3

A vulnerability exists where it possible to force Network Security Services NSS to sign CertificateVerify with PKCS1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerabilit...
