* SECURITY UPDATE: Remote arbitrary code execution, remote DoS.
* crypto/asn1/tasn_dec.c, asn1_d2i_ex_primitive(): Initialize 'ret' to avoid
  an infinite loop in some circumstances. [CVE-2006-2937]

  handle invalid long cipher list strings. [CVE-2006-3738]

  values (similar to Mozilla's libnss). Fixes CPU usage/memory DoS. [CVE-2006-2940]
* Updated patch in previous package version to fix a few corner-case
  regressions. (This reverts the changes to rsa_eay.c/rsa.h/rsa_err.c, which
  were determined to not be necessary).
