Insufficient Entropy In Key Generation Algorithm

The Network Time Protocol NTP is used to synchronize a computer's time with another referenced time source. It was found that because NTP's access control was based on a source IP address, an attacker could bypass source IP restrictions and send malicious control and configuration packets by...

A Go implementation of Poly1305 that makes sense

Poly1305 is a Message Authentication Code--a cryptographic primitive for authenticating a message with a shared secret key, like HMAC. Although its really a fraction of the complexity of e.g. elliptic curves, most of the implementations Ive read look decidedly like magic, mysteriously multiplying...

Sensitive Data Exposure

Overview All versions of rails-session-decoder are missing verification of the Message Authentication Code appended to the cookies. This may lead to decryption of cipher text thus exposing encrypted information. Recommendation No fix is currently available. Consider using an alternative module...

Unverifiable Symmetric Encryption

spring-cloud-config has a flaw which allows malicious manipulation of symmetric encryptions. The vulnerability exists because its default symmetric encryption does not use a Message Authentication Code MAC to verify the authenticity of encrypted message...

DEBIAN-CVE-2015-7848

An integer overflow can occur in NTP-dev.4.3.70 leading to an out-of-bounds memory copy operation when processing a specially crafted private mode packet. The crafted packet needs to have the correct message authentication code and a valid timestamp. When processed by the NTP daemon, it leads to ...

HP Integrated Lights-Out Information Disclosure Vulnerability (CNVD-2016-07089)

HP Integrated Lights-Out is used for remote management of servers. An information disclosure vulnerability exists in HP Integrated Lights-Out. A remote attacker could exploit this vulnerability to cause information disclosure via TLS CBC Padding and MAC errors...

OpenSSH MAC Verification Security Bypass Vulnerability

OpenSSH is a set of connection tools maintained by the OpenBSD Project Group for secure access to remote computers. A security bypass vulnerability exists in OpenSSH MAC Verification, which allows attackers to bypass security restrictions and perform unauthorized operations...

UBUNTU-CVE-2016-4955

ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service peer-variable clearing and association outage by sending 1 a spoofed crypto-NAK packet or 2 a packet with an incorrect MAC value at a certain time...

DEBIAN-CVE-2016-2085

The evmverifyhmac function in security/integrity/evm/evmmain.c in the Linux kernel before 4.5 does not properly copy data, which makes it easier for local users to forge MAC values via a timing side-channel attack...

ntp, ntpdate, sntp security update

CentOS Errata and Security Advisory CESA-2015:2231 Updated ntp packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common...

CVE-2010-2057

shared/util/StateUtils.java in Apache MyFaces 1.1.x before 1.1.8, 1.2.x before 1.2.9, and 2.0.x before 2.0.1 uses an encrypted View State without a Message Authentication Code MAC, which makes it easier for remote attackers to perform successful modifications of the View State via a padding oracl...

Fortinet FortiOS Input Validation Vulnerability

Fortinet FortiOS is a set of security operating system developed by the U.S. Fiat Fortinet company dedicated to FortiGate network security platform. The system provides users with firewall, antivirus, IPSec/SSL VPN, Web content filtering and anti-spam and other security features. A security...

PT-2015-1639 · Cisco +1 · Cisco Asa +1

Name of the Vulnerable Software and Affected Versions: Cisco Adaptive Security Appliance ASA Software version 9.15.21 Description: The issue is related to the TLS implementation in the Cavium cryptographic-module firmware, which does not verify the MAC field. This allows man-in-the-middle attacke...

ntpd restrictions bypass

message authentication code implementation is invalid and can be bypasses...

UBUNTU-CVE-2015-1798

The symmetric-key feature in the receive function in ntpproto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC...

SSL/TLS: CBC padding timing attack (lucky-13)

The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct...
