SECUNIA ADVISORY ID:
SA13566

VERIFY ADVISORY:
http://secunia.com/advisories/13566/

CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Crypt::ECB 1.x (PERL module)
http://secunia.com/product/4440/

DESCRIPTION:
Bennett R. Samowich has discovered a security issue in Crypt::ECB,
which makes it easier for malicious people to brute force passwords.

The security issue is caused due to an error, where plain texts
containing the ASCII character "0" is incorrectly encoded. This
results in a weaker encryption and encoding collisions and may e.g.
make it easier to brute force passwords.

The issue has been confirmed on version 1.1. Other versions may also
be affected.

SOLUTION:
Edit the source code to ensure that the ASCII character "0" is
correctly handled.

PROVIDED AND/OR DISCOVERED BY:
Bennett R. Samowich
