CVE-2017-11671 1 Gnu 1 Gcc 2026-06-17 2.1 LOW 4.0 MEDIUM
Under certain circumstances, the ix86_expand_builtin function in i386.c in GNU Compiler Collection (GCC) version 4.6, 4.7, 4.8, 4.9, 5 before 5.5, and 6 before 6.4 will generate instruction sequences that clobber the status flag of the RDRAND and RDSEED intrinsics before it can be read, potentially causing failures of these instructions to go unreported. This could potentially lead to less randomness in random number generation.
CVE-2015-9435 1 Dash10 1 Oauth Server 2026-06-17 7.5 HIGH 9.8 CRITICAL
The oauth2-provider plugin before 3.1.5 for WordPress has incorrect generation of random numbers.
CVE-2014-2362 1 Oleumtech 2 Sensor Wireless I\/o Module, Wio Dh2 Wireless Gateway 2026-06-17 7.8 HIGH N/A
OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules rely exclusively on a time value for entropy in key generation, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by predicting the time of project creation.
CVE-2013-20003 1 Silabs 10 Zgm130s037hgn, Zgm130s037hgn Firmware, Zgm2305a27hgn and 7 more 2026-06-16 7.9 HIGH 8.3 HIGH
Z-Wave devices from Sierra Designs (circa 2013) and Silicon Labs (using S0 security) may use a known, shared network key of all zeros, allowing an attacker within radio range to spoof Z-Wave traffic.
CVE-2012-6124 1 Call-cc 1 Chicken 2026-06-16 5.0 MEDIUM 5.3 MEDIUM
A casting error in Chicken before 4.8.0 on 64-bit platform caused the random number generator to return a constant value. NOTE: the vendor states "This function wasn't used for security purposes (and is advertised as being unsuitable)."
CVE-2011-4574 1 Polarssl 1 Polarssl 2026-06-16 7.5 HIGH 9.8 CRITICAL
PolarSSL versions prior to v1.1 use the HAVEGE random number generation algorithm. At its heart, this uses timing information based on the processor's high resolution timer (the RDTSC instruction). This instruction can be virtualized, and some virtual machine hosts have chosen to disable this instruction, returning 0s or predictable results.
CVE-2009-3278 1 Qnap 4 Ts-239 Pro, Ts-239 Pro Firmware, Ts-639 Pro and 1 more 2026-06-16 4.9 MEDIUM 5.5 MEDIUM
The QNAP TS-239 Pro and TS-639 Pro with firmware 2.1.7 0613, 3.1.0 0627, and 3.1.1 0815 use the rand library function to generate a certain recovery key, which makes it easier for local users to determine this key via a brute-force attack.
CVE-2009-3238 4 Canonical, Linux, Opensuse and 1 more 5 Ubuntu Linux, Linux Kernel, Opensuse and 2 more 2026-06-16 7.8 HIGH 5.5 MEDIUM
The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to "return the same value over and over again for long stretches of time."
CVE-2009-2367 1 Iomega 2 Storcenter Pro, Storcenter Pro Firmware 2026-06-16 7.5 HIGH 9.8 CRITICAL
cgi-bin/makecgi-pro in Iomega StorCenter Pro generates predictable session IDs, which allows remote attackers to hijack active sessions and gain privileges via brute force guessing attacks on the session_id parameter.
CVE-2008-3280 1 Openid 1 Openid 2026-06-16 4.3 MEDIUM 5.9 MEDIUM
It was found that various OpenID Providers (OPs) had TLS Server Certificates that used weak keys, as a result of the Debian Predictable Random Number Generator (CVE-2008-0166). In combination with the DNS Cache Poisoning issue (CVE-2008-1447) and the fact that almost all SSL/TLS implementations do not consult CRLs (currently an untracked issue), this means that it is impossible to rely on these OPs.
CVE-2008-0166 3 Canonical, Debian, Openssl 3 Ubuntu Linux, Debian Linux, Openssl 2026-06-16 7.8 HIGH 7.5 HIGH
OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems uses a random number generator that generates predictable numbers, which makes it easier for remote attackers to conduct brute force guessing attacks against cryptographic keys.
CVE-2002-20002 2026-06-16 N/A 5.4 MEDIUM
The Net::EasyTCP package before 0.15 for Perl always uses Perl's builtin rand(), which is not a strong random number generator, for cryptographic keys.
