RHEL 7 : nss and nspr (RHSA-2020:4076)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:4076 advisory. Network Security Services NSS is a set of libraries designed to support the cross-platform development of security-enabled client and server...

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: 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...

kernel: memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c allows DoS

A flaw was found in the Linux kernel. The Wireless configuration API functionality mishandles resource cleanup in nl80211getftmresponderstats function. An attacker able to trigger the resource cleanup code path could use this flaw to crash the system. The highest threat from this vulnerability is...

CVE-2020-12788

The CVE concerns CMAC verification in Microchip Atmel ATSAMA5 products. The issue stems from side-channel weaknesses (timing and power analysis) during CMAC verification, which could potentially expose sensitive information. Connected documents reiterate the affected target as ATSAMA5, but do not...

New Raccoon Attack Could Let Attackers Break SSL/TLS Encryption

A group of researchers has detailed a new timing vulnerability in Transport Layer Security TLS protocol that could potentially allow an attacker to break the encryption and read sensitive communication under specific conditions. Dubbed "Raccoon Attack," the server-side attack exploits a...
