CVE-2026-56016 CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources

CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources. The generateid method builds the session id from a MD5 digest of the process id, the epoch time, and the built-in rand function. All three are predictable, low-entropy sources: the PID i...

CVE-2026-7830

CVE-2026-7830 affects UltraVNC up to version 1.8.2.2 and concerns the MS-Logon II authentication. The DH key exchange uses parameters within 64-bit space (DH_MAX_BITS) and the private exponent is generated using a rng() that relies on three libc rand() calls seeded from time(NULL). This yields an...

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-2026-57082

Net::BitTorrent versions before 2.1.0 for Perl generate the MSE Diffie-Hellman private key with a non-cryptographic PRNG. The MSE Message Stream Encryption handshake derives its 160-bit Diffie-Hellman private key from Perl's rand, a non-cryptographic drand48-class generator seeded once per proces...

CVE-2026-57082

Net::BitTorrent for Perl, in versions before 2.1.0 (and specifically through 2.0.1 in some records), is vulnerable to a cryptographic failure because it uses a non-cryptographic PRNG (Perl's rand() ) to generate the MSE Diffie-Hellman private key in KeyExchange.pm. Because this PRNG is seeded onc...
