Nextcloud: Reduced purmations on encryption

OC\Security\SecureRandom::generate Reduced Permutations OC\Security\SecureRandom::generate will by default use a-Z0-9+/ 64 bytes character set. The numbers are not predictable, due to the use of randomint. Most notably the OC\Security\Crypto::encrypt method uses an IV with a length of 16 bytes. I...

CVE-2019-14007

CVE-2019-14007 describes a timing side-channel issue caused by non-time-constant comparison functions affecting Qualcomm Snapdragon components (closed-source) across multiple devices. The underlying problem could enable a local attacker to infer sensitive information (SUI-related) due to timing d...

EulerOS Virtualization 3.0.2.2 : libgcrypt (EulerOS-SA-2020-1498)

According to the versions of the libgcrypt package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext...

CVE-2020-10932

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

EulerOS 2.0 SP3 : libgcrypt (EulerOS-SA-2020-1400)

According to the versions of the libgcrypt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proxima...

CVE-2020-10932

CVE-2020-10932 affects Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker able to obtain precise side‑channel measurements (often in compromised environments like SGX enclaves) can recover the long‑term ECDSA private key by exploiting side channels in scalar multiplication, convertin...
