CVE-2019-17006

CVE-2019-17006 : In Network Security Services (NSS) prior to 3.46, several cryptographic primitives lacked input length checks, enabling a heap-based buffer overflow that could crash the application or, per in-document wording, potentially allow code execution. The issue is associated with NSS us...

Vulnerability fixed in NSS

A vulnerability has been fixed in NSS. The vulnerability allows a remote malicious party capable of performing a denial-of-service attack perform on servers compiled with the NSS library by sending sending multiple ChangeCipherSpec messages. Mozilla has released updates to fix the vulnerability...

DEBIAN-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 fla...

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: 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...

Moderate: Red Hat Security Advisory: nss and nspr security, bug fix, and enhancement update

An update for nss, nss-softokn, nss-util, and nspr is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available f...

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: 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: 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...
