Security Vulnerabilities fixed in Firefox 78 — Mozilla

When %2F was present in a manifest URL, Firefox's AppCache behavior may have become confused and allowed a manifest to be served from a subdirectory. This could cause the appcache to be used to service requests for the top level directory. A VideoStreamEncoder may have been freed in a race...

UBUNTU-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 secr...

CVE-2020-12402

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...

CVE-2020-7352

The GalaxyClientService component of GOG Galaxy runs with elevated SYSTEM privileges in a Windows environment. Due to the software shipping with embedded, static RSA private key, an attacker with this key material and local user permissions can effectively send any operating system command to the...

CVE-2020-10941

Arm Mbed TLS before 2.16.5 allows attackers to obtain sensitive information an RSA private key by measuring cache usage during an import...

FreeBSD : Mbed TLS -- Cache attack against RSA key import in SGX (056ea107-5729-11ea-a2f3-001cc0382b2f)

Janos Follath reports : If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported. The attack only requires access to fine grained measurements to cache usage...

Security advisory YSA-2020-02, YSA-2020-03 | Yubico | YubiKey

The libykpiv library, included in the Yubico PIV Tool project and the YubiKey Smart Card Minidriver, does not properly check embedded length fields during device communication. A maliciously-crafted PIV token could possibly misreport the returned length fields during RSA key generation. This coul...

GHSA-P9CM-R7JG-8Q3G Incorrect signature verification in SimpleSAMLphp

Background An incorrect check of return values in the signature validation utilities allows an attacker to get invalid signatures accepted as valid by forcing an error during validation. Description The SimpleSAMLXMLValidator class allows the verification of the XML digital signature of a SAML 1...
