Hello Earlier this year "Number Cruncher" already reported a valgrind error in function AES_cbc_encrypt and included a two-line patch to fix it.
Please see this post for reference: http://marc.info/?l=openssl-dev&m=123211846607090&w=2 Yesterday I ran into the same valgrind error message using OpenSSL 0.9.8k on RHEL5. The patch from this earlier post fixes the error. Since my x86_64 assembler knowledge is insufficient to verify the correctness of the patch I would request that someone checks it and applies it to CVS. Regards, Peter.
