Arbitrary Code Execution

ntpd is vulnerable to arbitrary code execution. A buffer overflow flaw was discovered in the ntpd daemon's NTPv4 authentication code. If ntpd was configured to use public key cryptography for NTP packet authentication, a remote attacker could use this flaw to send a specially-crafted request pack...

CVE-2018-21058

An issue was discovered on Samsung mobile devices with N7.0, O8.0 exynos7420 or Exynos 8890/8996 chipsets software. Cache attacks can occur against the Keymaster AES-GCM implementation because T-Tables are used; the Cryptography Extension CE is not used. The Samsung ID is SVE-2018-12761 September...

CVE-2019-11840

An issue was discovered in supplementary Go cryptography libraries, aka golang-googlecode-go-crypto, before 2019-03-20. A flaw was found in the amd64 implementation of golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa. If more than 256 GiB of keystream is generated, or if the...

CVE-2020-11501

GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 2018-07-16 because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks...

CVE-2020-11501

CVE-2020-11501 affects GnuTLS 3.6.x prior to 3.6.13. The DTLS client uses 32 null bytes instead of random values during DTLS negotiations, removing randomness and breaking DTLS security guarantees. Affected range starts at 3.6.3 (2018-07-16) due to a 2017-10-06 commit. The issue was fixed in 3.6....
