Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> RDMA/core: Prefer NLA_NUL_STRING<br /> <br /> These attributes are evaluated as c-string (passed to strcmp), but<br /> NLA_STRING doesn&amp;#39;t check for the presence of a \0 terminator.<br /> <br /> Either this needs to switch to nla_strcmp() and needs to adjust printf fmt<br /> specifier to not use plain %s, or this needs to use NLA_NUL_STRING.<br /> <br /> As the code has been this way for long time, it seems to me that userspace<br /> does include the terminating nul, even tough its not enforced so far, and<br /> thus NLA_NUL_STRING use is the simpler solution.
