CVE-2025-2814  (opens in a new tab)

How to fix?

Upgrade Debian:14 libcrypt-cbc-perl to version 3.07-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcrypt-cbc-perl package and not the libcrypt-cbc-perl package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

Crypt::CBC versions between 1.21 and 3.05 for Perl may use the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.

This issue affects operating systems where "/dev/urandom'" is unavailable.  In that case, Crypt::CBC will fallback to use the insecure rand() function.
