CVE-2026-7830

UltraVNC through 1.8.2.2 uses inadequate cryptography in the MS-Logon II authentication scheme rfbUltraVNCMsLogonIIAuth. In rfb/dh.cpp the Diffie-Hellman key exchange is performed with parameters that fit in an unsigned 64-bit integer DHMAXBITS controls the prime size. A 64-bit DH key can be brok...

CVE-2026-44040 UltraVNC vncauth.c uses time-seeded libc rand() to generate VNC authentication challenge bytes

UltraVNC through 1.8.2.2 uses a cryptographically weak pseudo-random number generator to produce VNC authentication challenge bytes. In rfb/vncauth.c:119-129, the vncRandomBytes function seeds libc rand with time0 + getpid + rand and generates a 16-byte challenge. The combined seed space is...

CVE-2026-9638

Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts. These versions use the built-in rand function, which is predictable and unsuitable for cryptography...

CVE-2026-9638

Crypt::PBKDF2 for Perl versions before 0.261630 are vulnerable because they generate salts with the built-in rand function, which is predictable and not suitable for cryptography. Affected component: Crypt::PBKDF2 (Perl). Root cause: use of insecure RNG for salts. Impact: cryptographic salts may ...

USN-8418-1 libcrypt-saltedhash-perl vulnerability

It was discovered that Crypt-SaltedHash incorrectly generated salts using a cryptographically weak pseudo-random number generator. An attacker could possibly use this issue to predict generated salts, leading to a weakening of cryptographic protections...

Astra Linux – Vulnerability in node-form-data

The use of insufficiently random values in form-data allows for HTTP Parameter Pollution HPP. This vulnerability is associated with the program file lib/formdata.Js. This issue affects form-data versions: 2.5.4, 3.0.0 – 3.0.3, 4.0.0 – 4.0.3...

CVE-2025-14972

Countermeasures for DPA within SYMCRYPTO engine on SixG301xxx devices are not sufficiently random and will eventually repeat. KSU keys using SYMCRYPTO will be impacted by this vulnerability...

Spring Boot: Spring Boot: Weak pseudo-random number generation can lead to information disclosure.

A flaw was found in Spring Boot. The $random.value property source utilizes a weak pseudo-random number generator PRNG, meaning the values it produces are not sufficiently random for use as cryptographic secrets. An attacker could potentially predict these values, which may lead to information...
