CVE-2025-1828 (GCVE-0-2025-1828)

Vulnerability from cvelistv5 – Published: 2025-03-10 23:51 – Updated: 2025-09-09 13:56

Title
Perl's Crypt::Random module after 1.05 and before 1.56 may use rand() function for cryptographic functions
Summary
Crypt::Random Perl package 1.05 through 1.55 may use rand() function, which is not cryptographically strong, for cryptographic functions. If the Provider is not specified and /dev/urandom or an Entropy Gathering Daemon (egd) service is not available Crypt::Random will default to use the insecure Crypt::Random::rand provider. In particular, Windows versions of perl will encounter this issue by default.
