Version: 3.04-3
Severity: normal

Hi,

The following vulnerability was published for libcrypt-cbc-perl.

CVE-2025-2814[0]:
| 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.

Upstream has released a new version 3.07 which fixes it by switching
to Crypt::URandom.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
