Vulnerability Details : CVE-2012-2742
Revelation 0.4.13-2 and earlier uses only the first 32 characters of a password followed by a sequence of zeros, which reduces the entropy and makes it easier for context-dependent attackers to crack passwords and obtain access to keys via a brute-force attack.
