[Chicken-users] [SECURITY] Vulnerability to algorithmic complexity attack due to incorrect randomization of symbol table

Hi all, It was discovered that our fix for CVE-2012-6125 was incorrect for the internal Scheme symbol table. The code that sets up the initial symbol table is run _before_ initializing the PRNG, which means the randomization factor uses the initial libc seed state. On most libc implementations

[Chicken-users] [SECURITY] Potential denial of service due to segfault in "length" on improper lists

Hi all, We just fixed a potential security issue in the standard Scheme length procedure. When length is called on an improper list, the underlying C function C_i_list incorrectly checks the head of the _input_ list for being a pair rather than the head of the part currently being traversed.
