The deprecated compatibility function clnt_create in the sunrpc module of
the GNU C Library (aka glibc) through 2.34 copies its hostname argument on
the stack without validating its length, which may result in a buffer
overflow, potentially resulting in a denial of service or (if an
application is not built with a stack protector enabled) arbitrary code
execution.

Bugs

Notes

Author Note
mdeslaur Ubuntu has stack protector enabled since 2006, so this issue is only a denial of service.
