CVE-2009-4269: Weak password hash generation

August 16, 2010 (updated January 26, 2011)

The password hash generation algorithm in this package performs a transformation that reduces the size of the set of inputs to SHA-1, which produces a small search space that makes it easier for local and possibly remote attackers to crack passwords by generating hash collisions, related to password substitution.
