CVE-2015-3006 1 Juniper 3 Junos, Qfx3500, Qfx3600 2026-06-17 6.8 MEDIUM 6.5 MEDIUM
On the QFX3500 and QFX3600 platforms, the number of bytes collected from the RANDOM_INTERRUPT entropy source when the device boots up is insufficient, possibly leading to weak or duplicate SSH keys or self-signed SSL/TLS certificates. Entropy increases after the system has been up and running for some time, but immediately after boot, the entropy is very low. This issue only affects the QFX3500 and QFX3600 switches. No other Juniper Networks products or platforms are affected by this weak entropy vulnerability.
CVE-2014-8422 2 Atos, Unify 8 Openscape Desk Phone Ip 35g, Openscape Desk Phone Ip 35g Eco, Openscape Desk Phone Ip 55g and 5 more 2026-06-17 6.8 MEDIUM 8.1 HIGH
The web-based management (WBM) interface in Unify (former Siemens) OpenStage SIP and OpenScape Desk Phone IP V3 devices before R3.32.0 generates session cookies with insufficient entropy, which makes it easier for remote attackers to hijack sessions via a brute-force attack.
CVE-2014-0691 1 Cisco 1 Webex Meetings Server 2026-06-17 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-2013-2260 1 Cryptocat Project 1 Cryptocat 2026-06-16 5.0 MEDIUM 9.8 CRITICAL
Cryptocat before 2.0.22: Cryptocat.random() Function Array Key has Entropy Weakness
CVE-2012-4687 1 Postoaktraffic 1 Awam Bluetooth Reader 2026-06-16 7.6 HIGH N/A
Post Oak AWAM Bluetooth Reader Traffic System does not use a sufficient source of entropy for private keys, which makes it easier for man-in-the-middle attackers to spoof a device by predicting a key value.
CVE-2008-2108 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2026-06-16 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-2008-1447 6 Canonical, Cisco, Debian and 3 more 8 Ubuntu Linux, Ios, Debian Linux and 5 more 2026-06-16 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-2001-0950 1 Valicert 1 Enterprise Validation Authority 2026-06-16 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.
