27 November 2014

Libksba could be made to crash or run programs if it opened a specially crafted file.



  • libksba - X.509 and CMS support library


Hanno Böck discovered that Libksba incorrectly handled certain S/MIME
messages or ECC based OpenPGP data. An attacker could use this issue to
cause Libksba to crash, resulting in a denial of service, or possibly
execute arbitrary code.
