CVE-2015-3405 7 Debian, Fedoraproject, Ntp and 4 more 13 Debian Linux, Fedora, Ntp and 10 more 2024-02-28 5.0 MEDIUM 7.5 HIGH
ntp-keygen in ntp 4.2.8px before 4.2.8p2-RC2 and 4.3.x before 4.3.12 does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys.
CVE-2017-13992 1 Loytec 2 Lvis-3me, Lvis-3me Firmware 2024-02-28 6.8 MEDIUM 8.1 HIGH
An Insufficient Entropy issue was discovered in LOYTEC LVIS-3ME versions prior to 6.2.0. The application does not utilize sufficiently random number generation for the web interface authentication mechanism, which could allow remote code execution.
CVE-2015-7764 1 Netflix 1 Lemur 2024-02-28 5.0 MEDIUM 7.5 HIGH
Lemur 0.1.4 does not use sufficient entropy in its IV when encrypting AES in CBC mode.
CVE-2017-0897 1 Expressionengine 1 Expressionengine 2024-02-28 5.0 MEDIUM 7.5 HIGH
ExpressionEngine version 2.x < 2.11.8 and version 3.x < 3.5.5 create an object signing token with weak entropy. Successfully guessing the token can lead to remote code execution.
CVE-2017-6030 1 Schneider-electric 6 Modicon M221, Modicon M221 Firmware, Modicon M241 and 3 more 2024-02-28 6.4 MEDIUM 6.5 MEDIUM
A Predictable Value Range from Previous Values issue was discovered in Schneider Electric Modicon PLCs Modicon M221, firmware versions prior to Version 1.5.0.0, Modicon M241, firmware versions prior to Version 4.0.5.11, and Modicon M251, firmware versions prior to Version 4.0.5.11. The affected products generate insufficiently random TCP initial sequence numbers that may allow an attacker to predict the numbers from previous values. This may allow an attacker to spoof or disrupt TCP connections.
CVE-2014-0691 1 Cisco 1 Webex Meetings Server 2024-02-28 5.0 MEDIUM 7.3 HIGH
Cisco WebEx Meetings Server before 1.1 uses meeting IDs with insufficient entropy, which makes it easier for remote attackers to bypass authentication and join arbitrary meetings without a password, aka Bug ID CSCuc79643.
CVE-2016-2564 1 Invisioncommunity 1 Invision Power Board 2024-02-28 4.3 MEDIUM 5.9 MEDIUM
Invision Power Services (IPS) Community Suite before 4.1.9 makes session hijack easier by relying on the PHP uniqid function without the more_entropy flag. Attackers can guess an Invision Power Board session cookie if they can predict the exact time of cookie generation.
CVE-2016-2858 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2024-02-28 1.9 LOW 6.5 MEDIUM
QEMU, when built with the Pseudo Random Number Generator (PRNG) back-end support, allows local guest OS users to cause a denial of service (process crash) via an entropy request, which triggers arbitrary stack based allocation and memory corruption.
CVE-2008-1447 6 Canonical, Cisco, Debian and 3 more 8 Ubuntu Linux, Ios, Debian Linux and 5 more 2024-02-28 5.0 MEDIUM 6.8 MEDIUM
The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug."
CVE-2008-2108 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-02-28 7.5 HIGH 9.8 CRITICAL
The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 64-bit systems, performs a multiplication that generates a portion of zero bits during conversion due to insufficient precision, which produces 24 bits of entropy and simplifies brute force attacks against protection mechanisms that use the rand and mt_rand functions.
CVE-2001-0950 1 Valicert 1 Enterprise Validation Authority 2024-02-28 7.5 HIGH 7.5 HIGH
ValiCert Enterprise Validation Authority (EVA) Administration Server 3.3 through 4.2.1 uses insufficiently random data to (1) generate session tokens for HSMs using the C rand function, or (2) generate certificates or keys using /dev/urandom instead of another source which blocks when the entropy pool is low, which could make it easier for local or remote attackers to steal tokens or certificates via brute force guessing.
